What does it mean to use "\v" here?
argp splits the documentation string on \v. The part before \v shows
up at the start of the --help output, while the part after appears
after the detailed help text for the arguments. [1]
sounds good. Thanks for explanations!
Happy to take all your other suggestions; I'll revise and resend the
patch series later in the week.
Thanks,
Stephen
