[PATCH JGIT] Add the signed-off in the commit text dialog

The user can see and edit the signed-off in the commit dialog
before committing.

For new lines in the commit dialog, use Text.DELIMITER for
plateform neutrality.

This patch only applies after the 2 previous patches.
If you want to, I could probably modify this patch so that it would
apply on the current origin.

The other two have been applied so no need to rebase.
 

Wouldn't "[.\r\n]" be easier to use here than "(.|\r|\n)"?

Huh.  So I can only push the checkbox once, and that after that
its just an idiot switch?

If that's really going to be how it is, maybe we should disable
the checkbox?

FWIW, git-gui actually looks for the user's Signed-off-by line in the
text buffer.  If it can't find it, then it appends it onto the end.
That way the user can delete the line and do the sign off again if
they messed up somehow.

And actually, given that this is a checkbox and not a button, maybe
we should be able to *delete* the SBO line when the user tries to
uncheck the checkbox.  Which then gets into, what if the user made
an edit to the text and changed the SBO line, should this box get
unchecked automatically by some form a listener on the text box?

Food for thought.  I'm not sure what it should be.  But if it were
a checkbox, as a user I'd like it to be bi-directional (both add
and remove my SBO) and also uncheck when I edit or delete the SBO
line in the message box.

He he, more challenging but it would be much better too!
I try to implement this when I have time.

And what should we do, when we commit a change from somebody else?
Sould we be able to modify the signed-off of the author?

Well, not by a fancy UI widget and automated tools.  But editing
the SBO line in the message buffer is fine, just like any other
part of the message.

IMHO, the SBO checkbox/button in the UI is only for *your* SBO,
as the committer.  That's how git-gui behaves and it seems to
work out nicely.
