Oh, I guess I got used to projects where people pay no attention to
patch comments. How about this:

Subject: [PATCH] git-svn: don't create master if another head exists

git-svn insists on creating the "master" head (unless it exists) on every
"fetch". It is useful that it gets created initially, when no head exists
- users expect this git convention of having a "master" branch on initial

However creating it when there already is another head does not provide any
value - the ref is never updated, so it just gets stale after a while.  Also,
some users find it annoying that it gets recreated, especially when they would
like the git branch names to follow SVN repository branch names. More
background in http://thread.gmane.org/gmane.comp.version-control.git/115030

Make git-svn skip the "master" creation if HEAD points at a valid head. This
means "master" does get created on initial "clone" but does not get recreated
once a user deletes it.
