It's a good point. I like to use placeholders that don't sound like a
real command (and failed a little here), for example,
`GIT_DEBUGGER=my-cool-debugger some-various-args`. It can be a challenge
to choose a placeholder that sounds fake but also doesn't sound too
informal (the above feels informal to me). I think the best way is to
show an example, that's a good idea. I'll come up with one and send
another round this week.

Thanks a bunch for having a look.
