Re: _arguments parsing of --help output

The only problem I can see is if the user-supplied specs contain those 
options, too. Currently _arguments does not discard additional
definitions but the first one takes precedence with respect to
argument handling (arguments of options):

  _arguments '-e:ea:(1 2)' -e -b -p

This will make `foo -e <TAB>' complete `1' and `2' but `foo -' lists
both (with auto-descriptions).

Hm, maybe we should do something about that.

The code in _arguments takes care that the user-supplied specs are
preferred over the automatically derived ones, though.
