postfaq 1.16

Except for individual scripts, I'm slowly abandoning CVS for either Git or Subversion everywhere I use a revision control system. Today, I converted my FAQs over to Subversion, which meant that the version numbers in the Id strings are no longer particularly significant. I therefore modified postfaq to not include the revision number in a subheader unless it contains a period.

While I was modifying it, I noticed that it could generate invalid Expires headers by translating the name of the month, depending on the locale. That's now fixed as well. I also rewrapped the documentation and improved the REQUIREMENTS section.

You can get the latest version from the postfaq distribution page.
