am: ignore leading whitespace before patch
Some web-based email clients prepend whitespace to raw message transcripts to workaround content-sniffing in some browsers. 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).
