Well, if you want to migrate your git-svn repository to something else,
it doesn't makes sense to add this limitation. I'd rather see this
"problem" advertized in the manual page, rather than a limitation added.

Note that using git filter-branch on a git-svn repository and still
expecting it to work with git-svn is IMHO wrong in so many ways that we
should not really try that hard to prevent the user doing something
stupid anyways.
