git-svn by default puts its Subversion-tracking refs directly in refs/remotes/*. This runs counter to Git's convention of using refs/remotes/$remote/* for storing remote-tracking branches. Furthermore, combining git-svn with regular git remotes run the risk of clobbering refs under refs/remotes (e.g. if you have a git remote called "tags" with a "v1" branch, it will overlap with the git-svn's tracking branch for the "v1" tag from Subversion. Even though the git-svn refs stored in refs/remotes/* are not "proper" remote-tracking branches (since they are not covered by a proper git remote's refspec), they clearly represent a similar concept, and would benefit from following the same convention. For example, if git-svn tracks Subversion branch "foo" at refs/remotes/foo, and you create a local branch refs/heads/foo to add some commits to be pushed back to Subversion (using "git svn dcommit), then it is clearly unhelpful of Git to throw warning: refname 'foo' is ambiguous. every time you checkout, rebase, or otherwise interact with the branch. The existing workaround for this is to supply the --prefix=quux/ to git svn init/clone, so that git-svn's tracking branches end up in refs/remotes/quux/* instead of refs/remotes/*. However, encouraging users to specify --prefix to work around a design flaw in git-svn is suboptimal, and not a long term solution to the problem. Instead, git-svn should default to use a non-empty prefix that saves unsuspecting users from the inconveniences described above. This patch will only affect newly created git-svn setups, as the --prefix option only applies to git svn init (and git svn clone). Existing git-svn setups will continue with their existing (lack of) prefix. Also, if anyone somehow prefers git-svn's old layout, they can recreate that by explicitly passing an empty prefix (--prefix "") on the git svn init/clone command line. The patch changes the default value for --prefix from "" to "origin/", updates the git-svn manual page, and fixes the fallout in the git-svn testcases. (Note that this patch might be easier to review using the --word-diff and --word-diff-regex=. diff options.)
