Subject: [PATCH] Use the original FileBlob path for filesystem access

FileBlob now remembers the full path that was passed to its constructor,
and uses that for performing filesystem access. FileBlob#path continues
to return a relative path as before. This ensures that you can call
methods like #size and #mode on FileBlobs with relative paths,
regardless of the current working directory.
