28For each NAME, specify how arguments are to be completed.
29If the -p option is supplied, or if no options are supplied, existing
30completion specifications are printed in a way that allows them to be
31reused as input. The -r option removes a completion specification for
32each NAME, or, if no NAMEs are supplied, all completion specifications.

147 btmap of compspec options (arguments to `-o'). PP, if non-null, gets 1
