Jonathan Nieder ba020ef5eb manpages: italicize git command names (which were in teletype font)
The names of git commands are not meant to be entered at the
commandline; they are just names. So we render them in italics,
as is usual for command names in manpages.

Using

	doit () {
	  perl -e 'for (<>) { s/\`(git-[^\`.]*)\`/'\''\1'\''/g; print }'
	}
	for i in git*.txt config.txt diff*.txt blame*.txt fetch*.txt i18n.txt \
	        merge*.txt pretty*.txt pull*.txt rev*.txt urls*.txt
	do
	  doit <"$i" >"$i+" && mv "$i+" "$i"
	done
	git diff

git-check-ref-format(1)
=======================
NAME
----
git-check-ref-format - Make sure ref name is well formed
SYNOPSIS
--------
'git check-ref-format' <refname>
DESCRIPTION
-----------
Checks if a given 'refname' is acceptable, and exits non-zero if
it is not.
A reference is used in git to specify branches and tags. A
branch head is stored under `$GIT_DIR/refs/heads` directory, and
a tag is stored under `$GIT_DIR/refs/tags` directory. git
imposes the following rules on how refs are named:
. It can include slash `/` for hierarchical (directory)
grouping, but no slash-separated component can begin with a
dot `.`;
. It cannot have two consecutive dots `..` anywhere;
. It cannot have ASCII control character (i.e. bytes whose
values are lower than \040, or \177 `DEL`), space, tilde `~`,
caret `{caret}`, colon `:`, question-mark `?`, asterisk `*`,
or open bracket `[` anywhere;
. It cannot end with a slash `/`.
These rules makes it easy for shell script based tools to parse
refnames, pathname expansion by the shell when a refname is used
unquoted (by mistake), and also avoids ambiguities in certain
refname expressions (see linkgit:git-rev-parse[1]). Namely:
. double-dot `..` are often used as in `ref1..ref2`, and in some
context this notation means `{caret}ref1 ref2` (i.e. not in
ref1 and in ref2).
. tilde `~` and caret `{caret}` are used to introduce postfix
'nth parent' and 'peel onion' operation.
. colon `:` is used as in `srcref:dstref` to mean "use srcref\'s
value and store it in dstref" in fetch and push operations.
It may also be used to select a specific object such as with
'git-cat-file': "git cat-file blob v1.3.3:refs.c".
