Actually, in Coldfusion regular expressions, "." does match *ANY*
character, including linefeeds and other control chars, printable or
otherwise. There is no "multi line mode" like in perl regular
expressions (or is it vi?) ..
I just tested to verify that, and it does work for code like this:
This is a test

is cool.
If you're stripping anchors, it *does* work.

Excellent point. It would still strip unwanted tags inside the comment
that were after the first closing comment -->, but obviously that's an
undesirable affect.
I don't know how to solve it other than documenting that stripping
comments might not provide desirable results.
I can actually think of a solution *NOT* using regular expressions that
would probably work but might take a considerable amount of code :)
So, for now I'll just document =) or just not strip comments.
