Tolerating empty path components in ref names means each ref does
not have a unique name. This creates difficulty for porcelains
that want to see if two branches are equal. Add a helper associating
to each ref a canonical name.
If a user asks a porcelain to create a ref "refs/heads//master",
the porcelain can run "git check-ref-format --print refs/heads//master"
and only deal with "refs/heads/master" from then on.

"git check-ref-format --branch" expands. Explain it.
The --branch argument is not optional.

'git check-ref-format' checks for the presence of at least one '/', the
idea being that there should be no refs directly below 'refs/', so there
should be a category like 'heads/' or 'tags/' in a refname.
Try and make this clearer in the man page.

We already skip over loose refs under $GIT_DIR/refs if the name
ends with ".lock", so creating a branch named "foo.lock" will not
appear in the output of "git branch", "git for-each-ref", nor will
its commit be considered reachable by "git rev-list --all".
In the latter case this is especially evil, as it may cause
repository corruption when objects reachable only through such a
ref are deleted by "git prune".
It should be reasonably safe to deny use of ".lock" as a ref suffix.
In prior versions of Git such branches would be "phantom branches";
you can create it, but you can't see it in "git branch" output.

This changes the rules for refnames to forbid:
(1) a refname that contains "@{" in it.
Some people and foreign SCM converter may have named their branches
as frotz@24 and we still want to keep supporting it.
However, "git branch frotz@{24}" is a disaster. It cannot even
checked out because "git checkout frotz@{24}" will interpret it as
"detach the HEAD at twenty-fourth reflog entry of the frotz branch".
(2) a refname that ends with a dot.
We already reject a path component that begins with a dot, primarily
to avoid ambiguous range interpretation. If we allowed ".B" as a
valid ref, it is unclear if "A...B" means "in dot-B but not in A" or
"either in A or B but not in both".
But for this to be complete, we need also to forbid "A." to avoid "in
B but not in A-dot". This was not a problem in the original range
notation, but we should have added this restriction when three-dot
notation was introduced.
Unlike "no dot at the beginning of any path component" rule, this
rule does not have to be "no dot at the end of any path component",
because you cannot abbreviate the tail end away, similar to you can
say "dot-B" to mean "refs/heads/dot-B".
For these reasons, it is not likely people created branches with these
names on purpose, but we have allowed such names to be used for quite some
time, and it is possible that people created such branches by mistake or
by accident.
To help people with branches with such unfortunate names to recover,
we still allow "branch -d 'bad.'" to delete such branches, and also allow
"branch -m bad. good" to rename them.

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

Following what appears to be the predominant style, format
names of commands and commandlines both as `teletype text`.
While we're at it, add articles ("a" and "the") in some
places, italicize the name of the command in the manual page
synopsis line, and add a comma or two where it seems appropriate.

Since the git-* commands are not installed in $(bindir), using
"git-command <parameters>" in examples in the documentation is
not a good idea. On the other hand, it is nice to be able to
refer to each command using one hyphenated word. (There is no
escaping it, anyway: man page names cannot have spaces in them.)
This patch retains the dash in naming an operation, command,
program, process, or action. Complete command lines that can
be entered at a shell (i.e., without options omitted) are
made to use the dashless form.
The changes consist only of replacing some spaces with hyphens
and vice versa. After a "s/ /-/g", the unpatched and patched
versions are identical.

This default regex now matches explicit values, and unfortunately in this
case gitlink was being matched by just 'link', causing the wrong inline
macro template to be applied. By renaming the macro, we can avoid being
matched by the wrong regex.
