git-svn: bugfix: allow SVN:: lib users to track the root of the repository

Eric Wong · Junio C Hamano · commit 308906fa6e98 · 2006-08-11T16:21:51.000-07:00
I'm not sure if anybody has hit this (besides me), but this
fixes the problem where I ran into while attempting to import a
small repo at the root level:  I ended up with all the commits, but
with no file/tree changes at all throughout the entire history.

Also, fix a warning if the commit message is not defined for revision 0.
