RE: --help trough _use_lo , but how with -h style?

["Andrej Borsenkow" <Andrej.Borsenkow@mow.siemens.ru>]

I am not sure what do you mean. _use_lo simply does very general parsing
of 'command --help' output. But note, that --help is de facto standard
for GNU long options; and help format is more or less (actually, much
less :-) similar between commands. What you want is a function that
would parse general output of arbitrary command and generate useful
completion out of this. I doubt that it ever be possible.

Please, note, that as far as I can tell --help parsing is used only in
three completion functions currently - _configure, _tar and _gdb. Of
these three I  believe that _tar and _gdb use it only for historical
reasons - the single command where this makes sense is _configure.

Note, that parsing of help text has many drawbacks. You cannot supply
description; you cannot define mutualy excluding options; you cannot
define mutually dependent options or option sets. I.e. _arguments is
much better suited - with the additional cost of writing separate
function for every command.

Are you aware about _arguments and it's possibilities?
