Eric Wong 4950eed520 git svn: info: correctly handle absolute path args ...

Calling "git svn info $(pwd)" would hit:
  "Reading from filehandle failed at ..."
errors due to improper prefixing and canonicalization.

Strip the toplevel path from absolute filesystem paths to ensure
downstream canonicalization routines are only exposed to paths
tracked in git (or SVN).

v2:
  Thanks to Andrej Manduch for originally noticing the issue
  and fixing my original version of this to handle
  more corner cases such as "/path/to/top/../top" and
  "/path/to/top/../top/file" as shown in the new test cases.

v3:
  Fix pathname portability problems pointed out by Johannes Sixt
  with a hint from brian m. carlson.
