Subject: [PATCH] git-gui: Correctly categorize tracking branches and heads.

Up until now git-gui did not support the new wildcard syntax used to
fetch any remote branch into a tracking branch during 'git fetch'. Now
if we identify a tracking branch as ending with the string '/*' then
we use for-each-ref to print out the reference names which may have
been fetched by that pattern.  We also now correctly filter any
tracking branches out of refs/heads, if they user has placed any there.
