[PATCH] Completion: Fix `_files -F '(pat ...)'`

[dana <dana@dana.is>]

_files doesn't support the `-F '(pat ...)'` syntax that _path_files itself
does. Just carrying the same check over from _path_files fixes it.

I noticed that this method can't support patterns containing white space,
though. For example, `-F '(a\ *b)'` yields an array with the patterns `a`,
`\ `, and `*b`. Would it be better to use something like
${(Q)${(Z<Cn>)ignvars[2,-2]}} here, or do we just say that if you need
white space you have to use an intermediate array?
