<title>Fetching a repository's specific commit on an arbitrary branch</title>
<para>
If the revision you're looking for is in the default branch
of the git repository you don't strictly need to specify
the branch name in the <varname>ref</varname> attribute.
</para>
<para>
However, if the revision you're looking for is in a future
branch for the non-default branch you will need to specify
the the <varname>ref</varname> attribute as well.

<para>
It is nice to always specify the branch which a revision
belongs to. Without the branch being specified, the
fetcher might fail if the default branch changes.
Additionally, it can be confusing to try a commit from a
non-default branch and see the fetch fail. If the branch
is specified the fault is much more obvious.
