Begin commit messages with two empty lines.

This makes editors like Emacs wrap the commit message correctly. With
no empty line between the commit message and the 'HG:' lines, the
'HG:' lines would be wrapped as if they belonged to the commit message
and so lose their significance to Mercurial.

This makes no difference to what is stored by the commit -- whitespace
was already stripped from the beginning and end of commit messages.
