I can't find any problems there either.

Sorry, what should this ignore-same be used for?

Yes. I'd be tempted to suggest that existing values be made modifiers so
by default it would ignore all other words except the command and the
modifiers `current' and `command' would be there to ignore those too.

Does every utility already pass down -F? We could encode what we want
in the argument to -F or maybe use a utility function which is called to
construct an appropriate list for the -F argument. The utility function
could either be called from _description in response to the styles or
directly from the commands own completion.

The reason I mention _arguments is that it might be nice if _arguments
could remove options from the list. If you imagine this completion

_arguments -s -S '-r[recursive]' '-f[force]' '-i[interactive]' \
  "*:file:_files -F words"

_arguments could see the -F option and remove instances of -r, -f and -i
from the parameter to -F. This might be particularly useful where there
are several types of non-option arguments and we only want to ignore
words which are for the current _arguments spec.

Yes, that wouldn't be nice. I'll try to think of other options.

And thanks for fixing the _conditions thing.
