Extract some utilities from git-svn to allow extracting Git::SVN.
Put them in a new module called Git::SVN::Utils. Yeah, not terribly original and it will be a dumping ground. But its better than having them in the main git-svn program. At least they can be documented and tested. * fatal() is used by many classes. * Change the $can_compress lexical into a function. This should be enough to extract Git::SVN. Signed-off-by: Michael G. Schwern <schwern@pobox.com> Signed-off-by: Junio C Hamano <gitster@pobox.com> Signed-off-by: Eric Wong <normalperson@yhbt.net>
