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.
