thesecommands by the old name, this patch doesn't go that far. It also leaves the usage() functions alone such that
whenthey report their own progname in the usage text, they do so under the old name. This would need to change at some
point,but I'm unclear on whether that would be for v14 or if it would be delayed.

The way things like 'git' work is that 'git thunk' just looks in a
designated directory for an executable called git-thunk, and invokes
it if it's found. If you want to invent your own git subcommand, you
can. I guess 'git help' wouldn't know to list it, but you can still
get the metacommand to execute it. That only works if you use a
standard naming, though. If the meta-executable has to hard-code the
names of all the individual executables that it calls, then you can't
really make that work.
