same logic as replacing [subcommand] with the output of subcommand, but
on the outbound side, via {subcommand}. this lets you do something like,
say:
!echo {!facts buh}
and that won't get interpreted until '{!facts buh}' is on its way out of
the bot. thus, you could also put '{!facts buh}' into the output of some
other command, like a countdown reminder
