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). Thanks to Andrej Manduch <amanduch@xxxxxxxxx> 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.
