[PATCH] Make git-mailsplit strip whitespace from the start of the mailbox file.

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

This will allow it to handle the files gotten through gmail's web interface via its 'Show original' option.
These files contain the mail headers and the mail body, but start with some whitespace.
Now you can give these files to git-am without having to remove the whitespace yourself.

Fixed.

The files from gmail only contain 1 mail per file, but having git-mailspit
massage these into a proper file that git-mailinfo can parse seems like
a sane solution to me.
