Remove CVS $Id$ tags from core

Yup, that's worth doing. However, my good friend grep also found this in the 6.x branch:

themes/engines/phptemplate/phptemplate.engine:// $Id$

Rolling a patch, one sec...

Found another one. Let's take care of both at the same time.

Also, I grepped the 7.x and 8.x branches and those are already clean. Only 6.x has these, so the version here is right.

Sorry, cross post (and identical patch, nice). But, while we're at it, let's be honest -- this is a minor bug (if it's a bug at all). ;)

That is interesting, the patches are ===, not just functionally identical.

There have been several issues recently which have addressed this in Drupal 7.x and 8.x, where these tags keep cropping up as new commits are made. I suspect we'll be chasing these for a while still.

Thanks, committed.
