[PATCH] Make git-mailinfo strip whitespace from the start of the mail file.

[Simon Sasburg <simon.sasburg@gmail.com>]

This allows you to use files gotten through gmail's web interface via its 'Show original' option.

Note that this doesn't exactly follow RFC 2822 as far as i can see, but i don't know if git prefers to be strict or tolerant in these cases, so i'm sending the patch anyway.

It certaily helps me, even if just a little bit.
