If we begin to parse -abc and that the parser knew about -a and -b, it

Of course in the case of -acb (supposing -c is not taking an argument) the
caller will have to be especially clever to do the same thing. We could
think about exposing an API to do so if it's really needed, but oh well...
Well, if the other parser is _also_ parse_options() (ie you just cascade
them incrementally in a loop), then the other parser should get it right
automatically. No?
Exactly. There are minor glitches wrt the help generation to deal
with, but for pure parsing issues yes, it will work.
Why not just provide some api-functions to return a strbuf of the short
and long options each?
parse_opt_short_help(strbuf *sb, options...);
parse_opt_long_help(strbuf *sb_long, options...);
That way multi-parseopt programs can get their help-texts done right
with very little extra work.
