The goal of this patch series is to check if good revisions are
ancestor of the bad revision without forking a process to launch
"git rev-list $good ^$bad".
This new version of this patch series does not use an "unparse_commit"
function anymore, we use "clear_commit_marks" instead.

This patch adds the "unparse_commit" function that returns a commit
into an unparsed state by freeing its data and resetting its fields
to 0.
Its parents are recursively unparsed too, because they might have
been changed. But its tree is not unparsed as it should not have
been modifed.
Note that as the "flags" and "used" fields may be used even if the
object is not parsed, we have to reset them anyway.

Currently git-blame outputs text from the commit messages
(e.g. the author name and the summary string) as-is, without
even providing any information about the encoding used for
the data. It makes interpreting the data in multilingual
environment very difficult.
This commit changes the blame implementation to recode the
messages using the rules used by other commands like git-log.
Namely, the target encoding can be specified through the
i18n.commitEncoding or i18n.logOutputEncoding options, or
directly on the command line using the --encoding parameter.
Converting the encoding before output seems to be more
friendly to the porcelain tools than simply providing the
value of the encoding header, and does not require changing
the output format.
If anybody needs the old behavior, it is possible to
achieve it by specifying --encoding=none.

The new function reduce_heads() is given a list of commits, and removes
ones that can be reached from other commits in the list. It is useful for
reducing the commits randomly thrown at the git-merge command and remove
redundant commits that the user shouldn't have given to it.
The implementation uses the get_merge_bases_many() introduced in the
previous commit. If the merge base between one commit taken from the list
and the remaining commits is the commit itself, that means the commit is
reachable from some of the other commits.

This attached patch introduces a single bit "use_terminator" in "struct
rev_info", which is normally false (i.e. most formats use separator
semantics) but by flipping it to true, you can ask for terminator
semantics just like oneline format does.
The function get_commit_format(), which is what parses "--pretty=" option,
now takes a pointer to "struct rev_info" and updates its commit_format and
use_terminator fields. It used to return the value of type "enum
cmit_fmt", but all the callers assigned it to rev->commit_format.
There are only two cases the code turns use_terminator on. Obviously, the
traditional oneline format (--pretty=oneline) is one of them, and the new
case is --pretty=tformat:... that acts like --pretty=format:... but flips
the bit on.
With this, "--pretty=tformat:%H %s" acts like --pretty=oneline.

Earlier, the callchain from pretty_print_commit() down to pp_title_line()
had an unwarranted assumption that the presense of "after_subject"
parameter, means the caller has already output MIME headers for
attachments. The parameter's primary purpose is to give extra header
lines the caller wants to place after pp_title_line() generates the
"Subject: " line.
This assumption does not hold when the user used the format.header
configuration variable to pass extra headers, and caused a message with
non-ASCII character to lack proper MIME headers (e.g. 8-bit CTE header).
The earlier logic also failed to suppress duplicated MIME headers when
"format-patch -s --attach" is asked for and the signer's name demanded
8-bit clean transport.
This patch fixes the logic by introducing a separate need_8bit_cte
parameter passed down the callchain. This can have one of these values:
-1 : we've already done MIME crap and we do not want to add extra header
to say this is 8bit in pp_title_line();
0 : we haven't done MIME and we have not seen anything that is 8bit yet;
1 : we haven't done MIME and we have seen something that is 8bit;
pp_title_line() must add MIME header.
It adds two tests by Jeff King who independently diagnosed this issue.

This fixes the pathspec interactive_add() passes to the underlying
git-add--interactive helper. When the command was run from a
subdirectory, cmd_add() already has gone up to the toplevel of the work
tree, and the helper will be spawned from there. The pathspec given on
the command line from the user needs to be adjusted for this.
This adds "validate_pathspec()" function in the callchain, but it does
not validate yet. The function can be changed to barf if there are
unmatching pathspec given by the user, but that is not strictly
necessary.

When the body of the commit log message contains a non-ASCII character,
format-patch correctly emitted the encoding header to mark the resulting
message as such. However, if the original message was fully ASCII, the
command line switch "-s" was given to add a new sign-off, and
the signer's name was not ASCII only, the resulting message would have
contained non-ASCII character but was not marked as such.
This was cherry-picked from the fix in 'master'

This removes the unnecessary indirection of "revs->prune_fn",
since that function is always the same one (or NULL), and there
is in fact not even an abstraction reason to make it a function
(i.e. its not called from some other file and doesn't allow us
to keep the function itself static or anything like that).
It then just replaces it with a bit that says "prune or not",
and if not pruning, every commit gets TREECHANGE.
That in turn means that
- if (!revs->prune_fn || (flags & TREECHANGE))
- if (revs->prune_fn && !(flags & TREECHANGE))
just become
- if (flags & TREECHANGE)
- if (!(flags & TREECHANGE))
respectively.
Together with adding the "single_parent()" helper function, the "complex"
conditional now becomes
if (!(flags & TREECHANGE) && rev->dense && single_parent(commit))
continue;
Also indirection of "revs->dense" checking is thrown away the
same way, because TREECHANGE bit is set appropriately now.

.. by not using quite so much indirection.
This currently grows the "struct commit" a bit, which could be avoided by
using a union for "util" and "indegree" (the topo-sort used to use "util"
anyway, so you cannot use them together), but for now the goal of this was

Also remove the "len" parameter, as:
(1) it was used as a max boundary, and every caller used ~0u
(2) we check for final NUL no matter what, so it doesn't help for speed.

a lot less local variables, this makes the code way more readable, and
easier to extend if needed.

Traditionally we had 16kB limit when formatting log messages for
output, because it was easier to arrange for the caller to have
a reasonably big buffer and pass it down without ever worrying
about reallocating.
This changes the calling convention of pretty_print_commit() to
lift this limit. Instead of the buffer and remaining length, it
now takes a pointer to the pointer that points at the allocated
buffer, and another pointer to the location that stores the
allocated length, and reallocates the buffer as necessary.
To support the user format, the error return of interpolate()
needed to be changed. It used to return a bool telling "Ok the
result fits", or "Sorry, I had to truncate it". Now it returns
0 on success, and returns the size of the buffer it wants in
order to fit the whole result.

A shallow commit is a commit which has parents, which in turn are
"grafted away", i.e. the commit appears as if it were a root.
Since these shallow commits should not be edited by the user, but
only by core git, they are recorded in the file $GIT_DIR/shallow.
A repository containing shallow commits is called shallow.
The advantage of a shallow repository is that even if the upstream
contains lots of history, your local (shallow) repository needs not
occupy much disk space.
The disadvantage is that you might miss a merge base when pulling
some remote branch.

Every single user actually wanted this only for commit objects, and we
have no reason to waste space on it for other object types. So just move
the structure member from the low-level "struct object" into the "struct

This leaves the commit object the same size, and removes one unnecessary
pointer from all other object allocations.
