When git-fetch was builtin-ized, the previous script was moved to
contrib/examples. Now, it is the sole remaining user for
'git fetch--tool'.
The fetch--tool code is still worth keeping around so people can
try out the old git-fetch.sh, for example when investigating
regressions from the builtinifaction.

Clarification: the following description only talks about "git
grep -h" without any other options and arguments.
Such a change cannot be breaking backward compatibility. "grep
-h" cannot be asking for suppressing filenames, as there is no
match pattern specified.

Treat an "-h" option as a request for help, rather than an
"Unknown commit -h" error.
"cherry -h" could be asking to compare histories that leads to
our HEAD and a commit that can be named as "-h". Strictly
speaking, that may be a valid refname, but the user would have to
say something like "tags/-h" to name such a pathological ref
already, so it is not such a big deal.
The "-h" option keeps its meaning even if preceded by other
options or followed by other arguments. This keeps the
command-line syntax closer to what parse_options would give and
supports shell aliases like 'alias cherry="git cherry -v"' a
little better.

Treat an "-h" option as a request for help, rather than a "Not a
valid object name" error.
"commit-tree -h" could be asking to create a new commit from a
treeish named "-h". Strictly speaking, such a pathological ref
name is possible, but the user would have to had said something
like "tags/-h" to name such a pathological already. commit-tree
is usually used in scripts with raw object ids, anyway.
For consistency, the "-h" option uses its new meaning even if
followed by other arguments.

This change is strictly about 'git merge-ours -h' without
any other options and arguments.
This change cannot break compatibility since merge drivers are
always passed '--', among other arguments.
Any usage string for this command is a lie, since it ignored its
arguments until now. Still, it makes sense to let the user know
the expected usage when asked.

This only changes the behavior of "git show-ref -h" without any
other options and arguments.
"show-ref -h" currently is short for "show-ref --head", which
shows all the refs/* and HEAD, as opposed to "show-ref" that
shows all the refs/* and not HEAD.
Does anybody use "show-ref -h"? It was in Linus's original, most
likely only because "it might be handy", not because "the command
should not show the HEAD by default for such and such reasons".
So I think it is okay if "show-ref -h" (but not "show-ref
--head") gives help and exits.
If a current script uses "git show-ref -h" without any other
arguments, it would have to be adapted by changing "-h" to
"--head".

This only changes the behavior of "git check-ref-format -h"
without any other options and arguments.
This change cannot be breaking backward compatibility, since any
valid refname must contain a /. Most existing scripts use
arguments such as "heads/$foo". If some script checks the
refname "-h" alone, git check-ref-format will still exit with
nonzero status, and the only detrimental side-effect will be a
usage string sent to stderr.

"unpack-file -h" could be asking to save the contents of a blob
named "-h". Strictly speaking, such a pathological ref name is
possible, but the user would have to had said something like
"tags/-h" to name such a pathological ref already. When used in
scripts, unpack-file is typically not passed a user-supplied tag
name directly.

I think this should directly go to 'maint'. I ejected it from the
series.
Thanks.

Thanks. I think something like this should go on top on maint, then
reverted in master.
Sorry for the trouble,

Delay search for a git directory until option parsing has finished.
None of the functions used in option parsing look for or read any
files other than stdin, so this is safe.

Why do you have inclusion of "exec_cmd.h" in [19/24]? As far as I can
tell, nothing you do in that patch depends on it.
According to c6dfb39 (remote-curl: add missing initialization of
argv0_path, 2009-10-13), this patch is necessary (and you must include
"exec_cmd.h") on MinGW, regardless of the "give help upon -h" topic.
I think this should be ejected from your series go directly to 'maint', or
am I mistaken?

You are right.
This command (in bash):
comm <(git grepc -l main\( *.c) <(git grepc -l extract_argv0 *.c)
shows programs in the 1st column that have main(), but do not call
git_extract_argv0_path. One remaining candidate is show-index.c, but its only
call-out is sha1_to_hex(), which doesn't use any other services.
http-fetch.c is the only file that needs this patch.

There is no need for "git <command> -h" to depend on being inside
a repository.

merge-recursive and diff --no-index are not able to use usage()
because their usage strings depend on the circumstances in which
they are called.

Since die() and warn() are already printf-like, it may be tempting
to do this, but this is wrong.
I do not want to vet all the existing call sites to usage() of make sure
that all of them _happen_ to pass constant strings that do not have any
'%' in them.
Much more importantly, without a patch to future-proof all existing
callsites to modify from
usage(blame_usage);
to
usage("%s", blame_usage);
everybody needs to remember that some *_usage strings are special and have
to double % in it forever, which is a maintenance nightmare.
Besides, the majority of usage strings are _expected_ to be constant.
That is an important difference from die/warn whose purpose is to diagnose
and give appropriate message to the situation (hence they benefit from
formatting).
I've renamed this to usagef() and updated your two callers to use it in
the version I queued to 'pu'.
Thanks.

Usage messages (for example, from "git merge-recursive -h") are
friendlier when not preceded by "fatal".
