Thanks, this sounds like the best solution. It should be a tiny bit more
efficient, too, though I doubt it matters much in practice.

s/list-name/&s/, to match the code (and your commit message).

Ditto here. Also, now that we have two similar modes, perhaps the
"--list" description above should become:
List all variables set in config file, along with their values.

Might it flow a little better to always enter format_config, and then
just return early (before writing the value) when show_key_only is set?

We usually avoid the extra space after redirection operators. But we
also usually match existing code. I'm not sure which is more evil in
this case. ;)

This one is the odd man out if you are following existing style,
though.
The rest of the patch looks good to me.
