Huh? I didn't write this test.

I had to use --whitespace=strip with git-am above.

I had to use the following patch to get the multi-fetch test to pass
with GIT_SVN_DELTA_FETCH=1. (I discovered it while running make -C t
full-svn-test)

Is it safe to assume that svk-mirrored URLs will _always_ be file://?
If so, then the delta fetching code should never be needed.

Also, unconditionally setting ($rev - 1) in the above patch disables the
ability to do squashed history[1] imports (not sure if anybody cares about
them, though).

But the above test breaks this one...
