How to edit "Author" in a patch ready to push

[Thomas Morley]

Hi,
I've newly set up LilyDev3 and used it for the first time creating a patch for
https://code.google.com/p/lilypond/issues/detail?id=4428
I had some heavy problems, because I wasn't aware that most steps
described here:
http://lilypond.org/doc/v2.19/Documentation/contributor/commit-access
needed to be redone. Should be sorted now.

Though, the current patch for 4428 shows:
Author: harm <address@hidden>

Is there any way to change it to:
Author: Thomas Morley <address@hidden>
?


(I edited .gitconfig to do this in the future, but too late for the 4428-patch)

Cheers,
  Harm
