Subject: git-svn: fix some issues for people migrating from older versions
X-Git-Tag: v1.5.1-rc1~155
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=d6d3346babaf19864ea104b0140279e62f32f7e3;p=git.git

git-svn: fix some issues for people migrating from older versions

 * Fixed logic for renaming old .rev_db -> .rev_db.$uuid

 * correctly handle manual migrations for those who decide to
   start use globbing to handle branches/tags over individual
   'fetch' keys
