Re: PATCH: _urls again (Re: setopt localoptions noautoremoveslash)

[Tanaka Akira <akr@jaist.ac.jp>]

This is another refinement for _urls.

* _urls is used as completion function of `curl'
 (http://curl.haxx.nu/)
* Use [[ ... ]] instead of [ ... ].
* Use (#b) in an argument of compset -P to extract info.
* Eliminate unused variable.
