Fork the topmost patch. Forking a patch means creating a verbatim copy
of it under a new name, and use that new name instead of the original
one in the current series. This is useful when a patch has to be
modified, but the original version of it should be preserved, e.g.
because it is used in another series, or for the history. A typical
sequence of commands would be: fork, edit, refresh.

If new_name is missing, the name of the forked patch will be the current
patch name, followed by \"-2\". If the patch name already ends in a
dash-and-number, the number is further incremented (e.g., patch.diff,
patch-2.diff, patch-3.diff).
