Actually it's all options, it's the evil GNU getopt's default behaviour
(it can be turned off by putting a "+" at the start of the option string).

If we can determine that a particular command is processing options in
this way, it would be nice to complet options accordingly. However,
by default options should only be completed before the first non-option
argument. In either case, options should never be completed after a "--".
I envision _arguments first of all deciding whether the command allows
options everywhere or not. This should be under the control of the
caller, via options to _arguments; possible values are "everywhere",
"only before first argument", "autodetect GNU getopt" (if possible).
_arguments must also check for a "--" argument, and not do option
completion (regardless of option style) if the cursor is after the "--".
All of this then lets it decide whether to complete options or not;
non-option arguments are always a possibility, though we might want to
be clever about handling arguments that start with "-".
