There are certain C99 features that might be nice to use in
our code base, but we've hesitated to do so in order to
avoid breaking compatibility with older compilers. But we
don't actually know if people are even using pre-C99
compilers these days.
One way to figure that out is to introduce a very small use
of a feature, and see if anybody complains. The strbuf code
is a good place to do this for a few reasons:
- it always gets compiled, no matter which Makefile knobs
have been tweaked.
- it's very stable; this definition hasn't changed in a
long time and is not likely to (so if we have to revert,
it's unlikely to cause headaches)
If this patch can survive a few releases without complaint,
then we can feel more confident that designated initializers
are widely supported by our user base. It also is an
indication that other C99 features may be supported, but not
a guarantee (e.g., gcc had designated initializers before
C99 existed).
And if we do get complaints, then we'll have gained some
data and we can easily revert this patch.

When color placeholders like %(color:red) are used in a
ref-filter format, we unconditionally output the colors,
even if the user has asked us for no colors. This usually
isn't a problem when the user is constructing a --format on
the command line, but it means we may do the wrong thing
when the format is fed from a script or alias. For example:
$ git config alias.b 'branch --format=%(color:green)%(refname)'
$ git b --no-color
should probably omit the green color. Likewise, running:
$ git b >branches
should probably also omit the color, just as we would for
all baked-in coloring (and as we recently started to do for
user-specified colors in --pretty formats).
This commit makes both of those cases work by teaching
the ref-filter code to consult want_color() before
outputting any color. The color flag in ref_format defaults
to "-1", which means we'll consult color.ui, which in turn
defaults to the usual isatty() check on stdout. However,
callers like git-branch which support their own color config
(and command-line options) can override that.
The new tests independently cover all three of the callers
of ref-filter (for-each-ref, tag, and branch). Even though
these seem redundant, it confirms that we've correctly
plumbed through all of the necessary config to make colors
work by default.

The color placeholders have traditionally been
unconditional, showing colors even when git is not otherwise
configured to do so. This was not so bad for their original
use, which was on the command-line (and the user could
decide at that moment whether to add colors or not). But
these days we have configured formats via pretty.*, and
those should operate correctly in multiple contexts.
In 3082517 (log --format: teach %C(auto,black) to respect
color config, 2012-12-17), we gave an extended placeholder
that could be used to accomplish this. But it's rather
clunky to use, because you have to specify it individually
for each color (and their matching resets) in the format.
We shied away from just switching the default to auto,
because it is technically breaking backwards compatibility.
However, there's not really a use case for unconditional
colors. The most plausible reason you would want them is to
redirect "git log" output to a file. But there, the right
answer is --color=always, as it does the right thing both
with custom user-format colors and git-generated colors.
So let's switch to the more useful default. In the
off-chance that somebody really does find a use for
unconditional colors without wanting to enable the rest of
git's colors, we provide a new %C(always,...) to enable the
old behavior. And we can remind them of --color=always in
the documentation.

When rev-list pretty-prints a commit, it creates a new
pretty_print_context and copies items from the rev_info
struct. We don't currently copy the "use_color" field,
though. Nobody seems to have noticed because the only part
of pretty.c that cares is the %C(auto,...) placeholder, and
presumably not many people use that with the rev-list
plumbing (as opposed to with git-log).
It will become more noticeable in a future patch, though,
when we start treating all user-format colors as auto-colors
(in which case it would become impossible to format colors
with rev-list, even with --color=always).

In most commands we load config before parsing command line
options, since it lets the latter override the former with a
simple variable assignment. In the case of for-each-ref,
though, we do it in the reverse order. This is OK with
the current code, since there's no interaction between the
config and command-line options.
However, as the ref-filter code starts to care about config
during verify_ref_format(), we'll want to make sure the
config is loaded. Let's bump the config to the usual spot
near the top of the function.
We can drop the comment there; it's impossible to keep a
"why we load the config" comment like this up to date with
every config option we might be interested in. And indeed,
it's already stale; we'd care about core.abbrev, for
instance, when %(objectname:short) is used.

Back in prehistoric times, our decision on whether or not to
show color by default relied on using a config callback that
either did or didn't load color config like color.diff.
When we introduced color.ui, we put it in the same boat:
commands had to manually respect it by using git_color_config()
or its git_color_default_config() convenience wrapper.
But in 4c7f1819b (make color.ui default to 'auto',
2013-06-10), that changed. Since then, we default color.ui
to auto in all programs, meaning that even plumbing commands
like "git diff-tree --pretty" might colorize the output.
Nobody seems to have complained in the intervening years,
presumably because the "is stdout a tty" check does a good
job of catching the right cases.
But that leaves an interesting curiosity: color.ui defaults
to auto even in plumbing, but you can't actually _disable_
the color via config. So if you really hate color and set
"color.ui" to false, diff-tree will still show color (but
porcelain like git-diff won't). Nobody noticed that either,
probably because very few people disable color.
One could argue that the plumbing should _always_ disable
color unless an explicit --color option is given on the
command line. But in practice, this creates a lot of
complications for scripts which do want plumbing to show
user-visible output. They can't just pass "--color" blindly;
they need to check the user's config and decide what to
send.
Given that nobody has complained about the current behavior,
let's assume it's a good path, and follow it to its
conclusion: supporting color.ui everywhere.
Note that you can create havoc by setting color.ui=always in
your config, but that's more or less already the case. We
could disallow it entirely, but it is handy for one-offs
like:
git -c color.ui=always foo >not-a-tty
when "foo" does not take a --color option itself.

The callback for parsing each formatting atom gets to see
only the atom struct (which it's filling in) and the text to
be parsed. This doesn't leave any room for it to behave
differently based on context known only to the ref_format.
We can solve this by passing in the surrounding ref_format
to each parser. Note that this makes things slightly awkward
for sort strings, which parse atoms without having a
ref_format. We'll solve that by using a dummy ref_format
with default parameters.

The ref-filter module currently provides a callback suitable
for parsing command-line --sort options. But since git-tag
also supports the tag.sort config option, it needs a
function whose implementation is quite similar, but with a
slightly different interface. The end result is that
builtin/tag.c has a copy-paste of parse_opt_ref_sorting().
Instead, let's provide a function to parse an arbitrary
sort string, which we can then trivially wrap to make the
parse_opt variant.

Calling verify_ref_format() doesn't just confirm that the
format is sane; it actually sets some global variables that
will be used later when formatting the refs. These logically
should belong to the ref_format, which would make it
possible to use multiple formats within a single program
invocation.
Let's move one such flag into the ref_format struct. There
are still others that would need to be moved before it would
be safe to use multiple formats, but this commit gives a
blueprint for how that should look.

The ref-filter module provides routines for formatting a ref
for output. The fundamental interface for the format is a
"const char *" containing the format, and any additional
options need to be passed to each invocation of
show_ref_array_item.
Instead, let's make a ref_format struct that holds the
format, along with any associated format options. That will
make some enhancements easier in the future:
1. new formatting options can be added without disrupting
existing callers
2. some state can be carried in the struct rather than as
global variables
For now this just has the text format itself along with the
quote_style option, but we'll add more fields in future patches.

When we put literal ANSI terminal codes into our test
scripts, it makes diffs on those scripts hard to read (the
colors may be indistinguishable from diff coloring, or in
the case of a reset, may not be visible at all).
Some scripts get around this by including human-readable
names and converting to literal codes with a git-config
hack. This makes the actual code diffs look OK, but test_cmp
output suffers from the same problem.
Let's use test_decode_color instead, which turns the codes

Users of the ref-filter code must call verify_ref_format()
before formatting any refs, but most ignore its return
value. This means we may print an error on a syntactically
bogus pattern, but keep going anyway.
In most cases this results in a fatal error when we actually
try to format a ref. But if you have no refs to show at all,
then the behavior is confusing: git prints the error from
verify_ref_format(), then exits with code 0 without showing
any output. Let's instead abort immediately if we know we
have a bogus format.
We'll output the usage information if we have it handy (just
like the existing call in cmd_for_each_ref() does), and
otherwise just die().
