Re: [PATCH] builtin-merge: give a proper error message for invalid strategies in config

would like to send a patch that changes the config parsing as well, so

Don't.  pull.* has always been defined as "list of strategies", and -s has
always been defined to take "a" strategy.

IOW, you don't need to break anything further.
