Adjust the patch format detection logic to ignore leading whitespace. So now you can apply patches from GMail with "git am" in three steps: 1. choose "show original" 2. tell the browser to "save as" (for example by pressing Ctrl+S) 3. run "git am" on the saved file This fixes a regression introduced by v1.6.4-rc0~15^2~2 (git-am foreign patch support: autodetect some patch formats, 2009-05-27). GMail support was first introduced to "git am" by v1.5.4-rc0~274^2 (Make mailsplit and mailinfo strip whitespace from the start of the input, 2007-11-01).

This requires passing the prefix down the call chain. This fixes two test cases for different reasons: * "unnormalized paths" is fixed because the .gitattribute-file-seeking code is not confused into reading the top-level file twice. * "relative paths" is fixed because the canonical pathnames are passed to get_check_attr() or get_all_attrs(), allowing them to match the pathname patterns as expected.
