stg-redo — Undo the last undo operation
If the last command was an undo, reset the patch stack to the state it had before the undo. Consecutive invocations of "stg redo" will undo the effects of consecutive invocations of "stg undo".
It is an error to run "stg redo" if the last command was not an undo.
- -n N, --number N
Undo the last N undos.
