Sometimes I accidentally try to fetch changes by doing a "git-svn fetch" in a git repository that is not connected to any SVN repository. Then git tells me that data from a previous version of git-svn exists, and migrates to a new git-svn layout. I think this is unexpected and unintended behavior and thus I consider this to be a bug.
How to reproduce:
$ git init tmp && cd tmp && git svn fetch
Initialized empty Git repository in /home/jo/tmp/.git/
Migrating from a git-svn v1 layout...
Data from a previous version of git-svn exists, but
.git/svn
(required for this version (1.7.11) of git-svn) does not exist.
Done migrating from a git-svn v1 layout
[svn-remote "svn"] unknown$
I would expect some output like "this is not a git-svn layout", but maybe I miss a point here?
