Andy Parkins noticed that the error message some "whole tree"
oriented commands emit is stated misleadingly when they refused
to run from a subdirectory.
We could probably allow some of them to work from a subdirectory
but that is a semantic change that could have unintended side
effects, so let's start at first by rewording the error message
to be easier to read without doing anything else to be safe.

The "read_or_die()" function would silently NOT die for a partial read,
and since it was of type "void" it obviously couldn't even return the
partial number of bytes read.
IOW, it was totally broken. This hopefully fixes it up.

With the new-and-improved write_in_full() semantics, where a partial write
simply always returns a real error (and always sets 'errno' when that
happens, including for the disk full case), a lot of the callers of
write_in_full() were just unnecessarily complex.
In particular, there's no reason to ever check for a zero length or
return: if the length was zero, we'll return zero, otherwise, if a disk
full resulted in the actual write() system call returning zero the
write_in_full() logic would have correctly turned that into a negative
return value, with 'errno' set to ENOSPC.
I really wish every "write_in_full()" user would just check against "<0"
now, but this fixes the nasty and stupid ones.

Recently git.git itself encountered a situation on its master and
next branches where git-describe stopped reporting 'v1.5.0-rc0-gN'
and instead started reporting 'v1.4.4.4-gN'. This appeared to be
a backward jump in version numbering.
maint o-------------------4
\ \
master o-o-o-o-o-o-o-5-o-C-o-W
The issue is that commit C in the diagram claims it is version
1.5.0, as the tag v1.5.0 is placed on commit 5. Yet commit W
claims it is version 1.4.4.4 as the tag v1.5.0 has an older tag
date than the v1.4.4.4 tag.
As it turns out this situation is very common. A bug fix applied
to maint and later merged into master occurs frequently enough that
it should Just Work Right(tm).
Rather than taking the first tag that gets found git-describe will
now generate a list of all possible tags and select the one which
has the most number of commits in common with HEAD (or whatever
revision the user requested the description of).
This rule is based on the principle shown in the diagram above.
There are a large number of commits on the primary development branch
'master' which do not appear in the 'maint' branch, and many of
these are already tagged as part of v1.5.0-rc0. Additionally these
commits are not in v1.4.4.4, as they are part of the v1.5.0 release
still being developed. The v1.5.0-rc0 tag is more descriptive of
W than v1.4.4.4 is, and therefore should be used.

If you do:
$ /bin/rm foo
$ git status
we used to say "git add ... to add content to commit". But
suggsting "git add" to record the deletion of a file is simply
insane.
So this rewords various things:
- The section header is the old "Changed but not updated",
instead of "Changed but not added";
- Suggestion is "git add ... to update what will be committed",
instead of "... to add content to commit";
- If there are removed paths, the above suggestion becomes "git
add/rm ... to update what will be committed";
- For untracked files, the suggestion is "git add ... to
include in what will be committed".

Often the user would do "/bin/rm foo" before telling git, but
then want to tell git about it. "git rm foo" however would fail
because it cannot unlink(2) foo.

removal happened.

This fixes another problem that Andy's case showed: git-fsck-objects
reports nonsensical results for corrupt objects.
There were actually two independent and confusing problems:
- when we had a zero-sized file and used map_sha1_file, mmap() would
return EINVAL, and git-fsck-objects would report that as an insane and
confusing error. I don't know when this was introduced, it might have
been there forever.
- when "parse_object()" returned NULL, fsck would say "object not found",
which can be very confusing, since obviously the object might "exist",
it's just unparseable because it's totally corrupt.
So this just makes "xmmap()" return NULL for a zero-sized object (which is
a valid thing pointer, exactly the same way "malloc()" can return NULL for
a zero-sized allocation). That fixes the first problem (but we could have
fixed it in the caller too - I don't personally much care whichever way it
goes, but maybe somebody should check that the NO_MMAP case does
something sane in this case too?).
And the second problem is solved by just making the error message slightly
clearer - the failure to parse an object may be because it's missing or
corrupt, not necessarily because it's not "found".

If the user tries to run a porcelainish command which requires
a working directory in a bare repository they may get unexpected
results which are difficult to predict and may differ from command
to command.
Instead we should detect that the current repository is a bare
repository and refuse to run the command there, as there is no
working directory associated with it.

The merge-recursive implementation in C inherited the invariant
that the on-file index file is written out and later read back
after any index operations and writing trees from the original
Python implementation. But it was only because the original
implementation worked at the scripting level.
There is no need to write out the index file after handling
every path.

My sp/mmap changes to pack-check.c modified the function such that
it expects packed_git.pack_size to be populated with the total
bytecount of the packfile by the caller.
But that isn't the case for packs obtained by git-http-fetch as
pack_size was not initialized before being accessed. This caused
verify_pack to think it had 2^32-21 bytes available when the
downloaded pack perhaps was only 305 bytes in length. The use_pack
function then later dies with "offset beyond end of packfile"
when computing the overall file checksum.
