Subject: Implement the 'goto' command
X-Git-Tag: v0.14.3~487
X-Git-Url: https://git.distorted.org.uk/~mdw/stgit/commitdiff_plain/994fdba73855eb93305d4722678b2af8266dbcb5

Implement the 'goto' command

Push/pop patches to/from the stack until the one given on the command
line becomes current. This is a shortcut for the 'push --to' or 'pop
--to' commands. There is no '--undo' option for 'goto'. Use the 'push'
command for this.
