Dan McGee 5162e69732 Documentation: rename gitlink macro to linkgit
Between AsciiDoc 8.2.2 and 8.2.3, the following change was made to the stock
Asciidoc configuration:

 # Inline macros.

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.

git-symbolic-ref(1)
===================
NAME
----
git-symbolic-ref - Read and modify symbolic refs
SYNOPSIS
--------
'git-symbolic-ref' [-q] [-m <reason>] <name> [<ref>]
DESCRIPTION
-----------
Given one argument, reads which branch head the given symbolic
ref refers to and outputs its path, relative to the `.git/`
directory. Typically you would give `HEAD` as the <name>
argument to see on which branch your working tree is on.
Give two arguments, create or update a symbolic ref <name> to
point at the given branch <ref>.
A symbolic ref is a regular file that stores a string that
begins with `ref: refs/`. For example, your `.git/HEAD` is
a regular file whose contents is `ref: refs/heads/master`.
OPTIONS
-------
-q, --quiet::
Do not issue an error message if the <name> is not a
symbolic ref but a detached HEAD; instead exit with
non-zero status silently.
-m::
Update the reflog for <name> with <reason>. This is valid only
when creating or updating a symbolic ref.
NOTES
-----
In the past, `.git/HEAD` was a symbolic link pointing at
`refs/heads/master`. When we wanted to switch to another branch,
we did `ln -sf refs/heads/newbranch .git/HEAD`, and when we wanted
to find out which branch we are on, we did `readlink .git/HEAD`.
This was fine, and internally that is what still happens by
default, but on platforms that do not have working symlinks,
or that do not have the `readlink(1)` command, this was a bit
cumbersome. On some platforms, `ln -sf` does not even work as
advertised (horrors). Therefore symbolic links are now deprecated
and symbolic refs are used by default.
git-symbolic-ref will exit with status 0 if the contents of the
symbolic ref were printed correctly, with status 1 if the requested
name is not a symbolic ref, or 128 if another error occurs.
