prefix_path() allocates new buffer. There's no reason for it to keep
the buffer for itself and waste memory.

309be813c9 update-index: migrate to parse-options API
--refresh and --really-refresh accept flags (like -q) and modify
an error indicator.  It might make sense to make the error
indicator global, but just pass the flags and a pointer to the error
indicator in a struct instead.

--cacheinfo wants 3 arguments.  Use the OPTION_LOWLEVEL_CALLBACK
extension to grab them and PARSE_OPT_NOARG to disallow the "sticked"
--cacheinfo=foo form.  (The resulting message

	$ git update-index --cacheinfo=foo
	error: option `cacheinfo' takes no value

is unfortunately incorrect.)

--assume-unchanged and --no-assume-unchanged probably should use the
OPT_UYN feature; but use a callback for now so the existing MARK_FLAG
and UNMARK_FLAG values can be used.

--stdin and --index-info are still constrained to be the last argument
(implemented using the OPTION_LOWLEVEL_CALLBACK extension).

--unresolve and --again consume all arguments that come after them
(also using OPTION_LOWLEVEL_CALLBACK).

The order of options matters.  Each path on the command line is
affected only by the options that come before it.  A custom
argument-parsing loop with parse_options_step() brings that about.

In exchange for all the fuss, we get the usual perks: support for
un-sticked options, better usage error messages, more useful -h
output, and argument parsing code that should be easier to tweak
in the future.

f07d6a1ad1 setup: save prefix (original cwd relative to toplevel) in startup_info
Save the path from the original cwd to the cwd at the end of the
setup procedure in the startup_info struct introduced in e37c1329
(2010-08-05).  The value cannot vary from thread to thread anyway,
since the cwd is global.

So now in your builtin command, instead of passing prefix around,
when you want to convert a user-supplied path to a cwd-relative
path, you can use startup_info->prefix directly.

Caveat: As with the return value from setup_git_directory_gently(),
startup_info->prefix would be NULL when the original cwd is not a
subdir of the toplevel.

Longer term, this would allow the prefix to be reused when several
noncooperating functions require access to the same repository (for
example, when accessing configuration before running a builtin).

b0b3a8b666 parse-options: allow git commands to invent new option types
parse-options provides a variety of option behaviors, including
OPTION_CALLBACK, which should take care of just about any sane
behavior.  All supported behaviors obey the following constraint:

 A --foo option can only accept (and base its behavior on)
 one argument, which would be the following command-line
 argument in the "unsticked" form.

Alas, some existing git commands have options that do not obey that
constraint.  For example, update-index --cacheinfo takes three
arguments, and update-index --resolve takes all later parameters as
arguments.

Introduces an OPTION_LOWLEVEL_CALLBACK backdoor to parse-options so
such option types can be supported without tempting inventors of other
commands through mention in the public API.  Commands can set the
callback field to a function accepting three arguments: the option
parsing context, the option itself, and a flag indicating whether the
the option was negated.  When the option is encountered, that function
is called to take over from get_value().  The return value should be
zero for success, -1 for usage errors.

Thanks to Stephen Boyd for API guidance.

b57c68a69e parse-options: never suppress arghelp if LITERAL_ARGHELP is set
The PARSE_OPT_LITERAL_ARGHELP flag allows a program to override the
standard "<argument> for mandatory, [argument] for optional" markup in
its help message.  Extend it to override the usual "no text for
disallowed", too (for the PARSE_OPT_NOARG | PARSE_OPT_LITERAL_ARGHELP
case, which was previously meaningless), to be more intuitive.

The motivation is to allow update-index to correctly advertise

	--cacheinfo <mode> <object> <path>
	                      add the specified entry to the index

while abusing PARSE_OPT_NOARG to disallow the "sticked form"

	--cacheinfo=<mode> <object> <path>

c1f4ec9ef4 parse-options: do not infer PARSE_OPT_NOARG from option type
Simplify the "takes no value" error path by relying on PARSE_OPT_NOARG
being set correctly.  That is:

 - if the PARSE_OPT_NOARG flag is set, reject --opt=value
   regardless of the option type;
 - if the PARSE_OPT_NOARG flag is unset, accept --opt=value
   regardless of the option type.

This way, the accepted usage more closely matches the usage advertised
with --help-all.

No functional change intended, since the NOARG flag is only used
with "boolean-only" option types in existing parse_options callers.

5c400ed2e0 parse-options: sanity check PARSE_OPT_NOARG flag
Some option types cannot use an argument --- boolean options that
would set a bit or flag or increment a counter, for example.  If
configured in the flag word to accept an argument anyway, the result
is an argument that is advertised in "program -h" output only to be
rejected by parse-options::get_value.

Luckily all current users of these option types use PARSE_OPT_NOARG
and do not use PARSE_OPT_OPTARG.  Add a check to ensure that that
remains true.  The check is run once for each invocation of
parse_option_start().

a02dd4ff7d parse-options: move NODASH sanity checks to parse_options_check
A dashless switch (like '(' passed to 'git grep') cannot be negated,
cannot be attached to an argument, and cannot have a long form.
Currently parse-options runs the related sanity checks when the
dashless option is used; better to always check them at the start of
option parsing, so mistakes can be caught more quickly.

The error message at the new call site is less specific about the
nature of the error, for simplicity.  On the other hand, it prints
which switch was problematic.  Before:

	fatal: BUG: dashless options can't be long

After:

	error: BUG: switch '(' uses feature not supported for dashless options

1e5ce570ca parse-options: clearer reporting of API misuse
The PARSE_OPT_LASTARG_DEFAULT flag is meant for options like
--contains that (1) traditionally had a mandatory argument and
(2) have some better behavior to use when appearing in the final
position.  It makes no sense to combine this with OPTARG, so ever
since v1.6.4-rc0~71 (parse-options: add parse_options_check to
validate option specs, 2009-07-09) this mistake is flagged with

	error: `--option` uses incompatible flags LASTARG_DEFAULT and OPTARG

and an exit status representing an error in commandline usage.

Unfortunately that which might confuse scripters calling such an
erroneous program into thinking the _script_ contains an error.
Clarify that it is an internal error by dying with a message beginning
"error: BUG: ..." and status 128.

While at it, clean up parse_options_check to prepare for more checks.

Long term, it would be nicer to make such checks happen at compile
time.

commit introducing this function cb9d398 (parse-options: add

should be called from parse_options_start(). However, the implementation

60aa9cf8f3 Documentation: document show -s
Git's diff machinery has supported a -s (silence diff output) option
as far back as v0.99~900 (Silent flag for show-diff, 2005-04-13), but
the option is only advertised in an odd corner of the git diff-tree
manual.

The main use is to retrieve basic metadata about a commit:

	git show -s rev

Explain this in the 'git log' manual and provide an example in the
'git show' examples section.  This is kind of a cop-out, since it
would be more useful to explain it in the 'git show' manual proper,
which says:

	The command takes options applicable to the git
	diff-tree command to control how the changes the
	commit introduces are shown.

	This manual page describes only the most frequently
	used options.

Fixing that is a larger task for another day.

24305cd700 apply: don't segfault on binary files with missing data
Usually when applying a binary diff generated without
--binary, it will be rejected early, as we don't even have
the full sha1 of the pre- and post-images.

However, if the diff is generated with --full-index (but not
--binary), then we will actually try to apply it. If we have
the postimage blob, then we can take a shortcut and never
even look at the binary diff at all (e.g., this can happen
when rebasing changes within a repository).

If we don't have the postimage blob, though, we try to look
at the actual fragments, of which there are none, and get a
segfault. This patch checks explicitly for that case and
complains to the user instead of segfaulting. We need to
keep the check at a low level so that the "shortcut" case
above continues to work.

We also add a test that demonstrates the segfault. While
we're at it, let's also explicitly test the shortcut case.
