completing-read to get an argument for an interactive command. The argument is a non-intuitive word (required for my application), so the completion list looks like this:
Possible completions are: faz foo bar baz
I'd like it to also show some help, something like this:
Possible completions are: faz Pogo quote part 2 foo Regular fubar bar All the soap baz Pogo quote part 1
Is there a straight-forward way to accomplish this, or something similar?
