cg-Xlib: make showdate show timezone

This makes timezones show up again in showdate's default format. Hopefully, this also makes showdate a little more portable.

It also speeds things up a little, by avoiding an extra fork.

Dear diary, on Sun, Jun 12, 2005 at 01:40:57PM CEST, I got a letter where Dan Holmsand <[email protected]> told me that...

Thanks, applied. But what's the point of calling date with LANG=C? If the user wants his locale to get used, why prevent him?

<Espy> be careful, some twit might quote you out of context..

Because otherwise, you won't get an RFC-2822 date (which is what you explicitly wanted a couple of days ago, and what we had before).

Also, it would look pretty awkward to have parts of the output localized
(the date string), and all other parts not ("author", "date", whatnot).
