+OK, quick. How do you rename all whatever.c-or-h files to old.whatever.c-or-h
+with wildcards instead of slices?

Well, this is as quick as I can get :-)

First, some honesty:  I have never done exactly what you ask, so I didn't
know if the way I wanted to do it would work.  So, I resolved to try it
exactly once, the way I assumed it would work.  If that didn't fly, I would
admit it.  Praise be to Allah, it did ;^)

First, I used Arp's copy command.  I don't know if C='s 1.3.2 will do this,
or not, but the Arp pattern matching library does it just fine.  Use the line

copy #?.(c|h) old.#?

Works like a champ.  And this is how I expected it to work!  I expect a `#?'
in the 2nd expression to resolve to all of the characters in the current 
filename, which is gotten from the 1st expression.

Admittedly, one can construct convoluted examples that won't be doable this
way.  Come up with a useful one, though, and I'll be impressed...
