Refuse to use $VISUAL and fall back to $EDITOR if TERM is unset
or set to "dumb". Traditionally, VISUAL is set to a screen
editor and EDITOR to a line-based editor, which should be more
useful in that situation.
vim, for example, is happy to assume a terminal supports ANSI
sequences even if TERM is dumb (e.g., when running from a text
editor like Acme). git already refuses to fall back to vi on a
dumb terminal if GIT_EDITOR, core.editor, VISUAL, and EDITOR are
unset, but without this patch, that check is suppressed by
VISUAL=vi.

The current technical documentation for the packfile protocol is both
sparse and incorrect. This documents the fetch-pack/upload-pack and
send-pack/ receive-pack protocols much more fully.
Add documentation from Shawn's upcoming http-protocol docs that is
shared by the packfile protocol. protocol-common.txt describes ABNF
notation amendments, refname rules and the packet line format.
Add documentation on the various capabilities supported by the
upload-pack and receive-pack protocols. protocol-capabilities.txt
describes multi-ack, thin-pack, side-band[-64k], shallow, no-progress,
include-tag, ofs-delta, delete-refs and report-status.

Since a0e4639 (filter-branch: fix ref rewriting with
--subdirectory-filter, 2008-08-12) git-filter-branch has done
nearest-ancestor rewriting when using a --subdirectory-filter.
However, that rewriting strategy is also a useful building block in
other tasks. For example, if you want to split out a subset of files
from your history, you would typically call
git filter-branch -- <refs> -- <files>
But this fails for all refs that do not point directly to a commit
that affects <files>, because their referenced commit will not be
rewritten and the ref remains untouched.
The code was already there for the --subdirectory-filter case, so just
introduce an option that enables it independently.

Handling $filter_subdir in the usual way requires a separate case at
every use, because the variable is empty when unused.
Furthermore, --subdirectory-filter supplies its own '--', and if the user
provided one himself, such as in
git filter-branch --subdirectory-filter subdir -- --all -- subdir/file
an extra '--' was used as path filter in the call to git-rev-list that
determines the commits that shall be rewritten.
To keep the argument handling sane, we filter $@ to contain only the
non-revision arguments, and store all revisions in $ref_args. The
$ref_args are easy to handle since only the SHA1s are needed; the
actual branch names have already been stored in $tempdir/heads at this
point.
An extra separating -- is only required if the user did not provide
any non-revision arguments, as the latter disambiguate the
$filter_subdir following after them (or fail earlier because they are
ambiguous themselves).
Thanks to Johannes Sixt for suggesting this solution.

Some new callers would want to use printf-like formatting, when issuing
their usage messages. An option is to change usage() itself also be like
printf(), which would make it similar to die() and warn().
But usage() is typically fixed, as opposed to die() and warn() that gives
diagnostics depending on the situation. Indeed, the majority of strings
given by existing callsites to usage() are fixed strings. If we were to
make usage() take printf-style format, they all need to be changed to have
"%s" as their first argument.
So instead, introduce usagef() so that limited number of callers can use
it.

http-push already knows how to dump usage if it is given no options, but
it interprets '-h' as the URL to a remote repository:
$ git http-push -h
error: Cannot access URL -h/, return code 6
Dump usage instead. Humans wanting to pass the URL -h/ to curl for some
reason can use 'git http-push -h/' explicitly. Scripts expecting to
access an HTTP repository at URL '-h' will break, though.
Also delay finding a git directory until after option parsing, so
"http-push -h" can be used outside any git repository.

"-p" means "generate patch" in 'git log' and 'git diff', so it's
quite surprising that it means "suppress diffstat" in
'git format-patch'.
Keep the "-p" option for backward compatibility, but add
"--no-stat" as a more intuitive synonym. For backward compatibility
with scripts, we must allow combinations of --stat and --no-stat.

To simplify reading the documentation for format-patch, remove the
description of common diff options that are not useful for the
purpose of the command (i.e. "Prepare patches for e-mail submission").
Specifically, this removes the description of the following options:
--raw
-z
--color
--no-color
--color-words
--diff-filter
-S
--pickaxe-all
--pickaxe-regex
-R
--relative
--exit-code

Jeff King recently reinstated -p to suppress the default diffstat
(as -p used to work before 68daa64, about 14 months ago).
However, -p is also needed in combination with certain options
(e.g. --stat or --numstat) in order to produce any patch at all.
The documentation does not mention this.
Since the purpose of format-patch is to produce a patch that
can be emailed, it does not make sense that certain combination
of options will suppress the generation of the patch itself.
Therefore:
* Update 'git format-patch' to always generate a patch.
* Since the --name-only, --name-status, and --check suppresses
the generation of the patch, disallow those options,
and remove the description of them in the documentation.
* Remove the reference to -p in the description of -U.
* Remove the descriptions of the options that are synonyms for -p
plus another option (--patch-with-raw and --patch-with-stat).
* While at it, slightly tweak the description of -p itself
to say that it generates "plain patches", so that you can
think of -p as "plain patch" as an mnemonic aid.

"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.

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.
