Create a new, empty patch on the current stack. The new patch is
created on top of the currently applied patches, and is made the new

included in the patch -- that is handled by linkstg:refresh[].
The given name must be unique in the stack, and may only contain
alphanumeric characters, dashes and underscores. If no name is given,
one is generated from the first line of the patch's commit message.
An editor will be launched to edit the commit message to be used for
the patch, unless the '--message' flag already specified one. The
