The prior patch uses "/**" to denote "documentation"
comments that we pulled from api-strbuf.txt. Let's use a
consistent style for similar comments that were already in
strbuf.h.

Some of strbuf is documented as comments above functions,
and some is separate in Documentation/technical/api-strbuf.txt.
This makes it annoying to find the appropriate documentation.
We'd rather have it all in one place, which means all in the
text document, or all in the header.
Let's choose the header as that place. Even though the
formatting is not quite as pretty, this keeps the
documentation close to the related code. The hope is that
this makes it easier to find what you want (human-readable
comments are right next to the C declarations), and easier
for writers to keep the documentation up to date.
This is more or less a straight import of the text from
api-strbuf.txt into C comments, complete with asciidoc
formatting. The exceptions are:
1. All comments created in this way are started with "/**"
to indicate they are part of the API documentation. This
may help later with extracting the text to pretty-print
it.
2. Function descriptions do not repeat the function name,
as it is available in the context directly below. So:
`strbuf_add`::
Add data of given length to the buffer.
from api-strbuf.txt becomes:
/**
* Add data of given length to the buffer.
*/
void strbuf_add(struct strbuf *sb, const void *, size_t);
As a result, any block-continuation required in asciidoc
for that list item was dropped in favor of straight
blank-line paragraph (since it is not necessary when we
are not in a list item).
3. There is minor re-wording to integrate existing comments
and api-strbuf text. In each case, I took whichever
version was more descriptive, and eliminated any
redundancies. In one case, for strbuf_addstr, the api
documentation gave its inline definition; I eliminated
this as redundant with the actual definition, which can
be seen directly below the comment.
4. The functions in the header file are re-ordered to match
the ordering of the API documentation, under the
assumption that more thought went into the grouping
there.

A request to store an empty note via "git notes" meant to remove

The plan for the push.default transition had all along been
to use the "simple" method rather than "upstream" as a
default if the user did not specify their own push.default
value. Commit 11037ee (push: switch default from "matching"
to "simple", 2013-01-04) tried to implement that by moving
PUSH_DEFAULT_UNSPECIFIED in our switch statement to
fall-through to the PUSH_DEFAULT_SIMPLE case.
When the commit that became 11037ee was originally written,
that would have been enough. We would fall through to
calling setup_push_upstream() with the "simple" parameter
set to 1. However, it was delayed for a while until we were
ready to make the transition in Git 2.0.
And in the meantime, commit ed2b182 (push: change `simple`
to accommodate triangular workflows, 2013-06-19) threw a
monkey wrench into the works. That commit drops the "simple"
parameter to setup_push_upstream, and instead checks whether
the global "push_default" is PUSH_DEFAULT_SIMPLE. This is
right when the user has explicitly configured push.default
to simple, but wrong when we are a fall-through for the
"unspecified" case.
We never noticed because our push.default tests do not cover
the case of the variable being totally unset; they only
check the "simple" behavior itself.

The "__attribute__" flag may be a noop on some compilers.
That's OK as long as the code is correct without the
attribute, but in this case it is not. We would typically
end up with a struct that is 2 bytes too long due to struct
padding, breaking both reading and writing of bitmaps.
Instead of marshalling the data in a struct, let's just
provide helpers for reading and writing the appropriate
types. Besides being correct on all platforms, the result is
more efficient and simpler to read.

Even though setup_user_tool assigns the exit status from "eval
$merge_tool_cmd" to $status, the variable is overwritten by the
function it calls next, check_unchanged, without ever getting looked
at by anybody. And "return $status" at the end of this function
returns the value check_unchanged assigned to it (which is the same
as the value the function returns). Which makes the assignment a
no-op.
Remove it.

If the user specifiers "normal" for a foreground color, this
should be a noop (while this may sound useless, it is the
only way to specify an unchanged foreground color followed
by a specific background color).
We also check that color "-1" does the same thing. This is
not documented, but has worked forever, so let's make sure
we keep supporting it.

Most of git-config's command line options use OPT_BIT to
choose an action, and then parse the non-option arguments
in a context-dependent way. However, --get-color and
--get-colorbool are unlike the rest of the options, in that
they are OPT_STRING, taking the option name as a parameter.
This generally works, because we then use the presence of
those strings to set an action bit anyway. But it does mean
that the option-parser will continue looking for options
even after the key (because it is not a non-option; it is an
argument to an option). And running:
git config --get-color some.key -1
(to use "-1" as the default color spec) will barf, claiming
that "-1" is not an option. Instead, we should treat
--get-color and --get-colorbool as action bits, just like
--add, --get, and all the other actions, and then check that
the non-option arguments we got are sane. This fixes the
weirdness above, and makes those two options like all the
others.
This "fixes" a test in t4026, which checked that feeding
"-2" as a color should fail (it does fail, but prior to this
patch, because parseopt barfed, not because we actually ever
tried to parse the color).
This also catches other errors, like:
git config --get-color some.key black blue
which previously silently ignored "blue" (and now will
complain that you gave too many arguments).
There are some possible regressions, though. We now disallow
these, which currently do what you would expect:
# specifying other options after the action
git config --get-color some.key --file whatever
# using long-arg syntax
git config --get-color=some.key
However, we have never advertised these in the
documentation, and in fact they did not work in some older
versions of git. The behavior was apparently switched as an
accidental side effect of d64ec16 (git config: reorganize to
use parseopt, 2009-02-21).
