Comment cleanup in common.test

Patched fine, looks good.

Thanks for the cleanup! One standards fix and one question:

This should be one line, 80 chars or less. I'd suggest making the description a little more generic and moving the list of function names to a second paragraph if desired.

While we're changing this, do we want to add parens for valid_url()?

re-rolled, it seems that the function names have been taken care of.

picked up from the novice queue.

I just went through and confirmed all the other fixes were covered by #899444: Declutter "System" test group by applying coding standards fixes to common.test. Thanks @LSU_JBob!

Committed to 8.x. Thanks.

I think we can probably backport this cleanup too.

D7 backport.

Yep.

Committed and pushed to 7.x. Thanks!
