Fix Bug 1192771 by replacing regular expressions with static node names.

Since I needed to fix up some comments in this commit anyway, I also
cleaned line length on several other comments while I was here.  If anyone
really has a problem with doing both at once, I'm happy to separate
these into separate commits.

This reverts commit 5bfdfbf86da0237d7cddc617315be9efce326127.  It included
some tidying up of comments that weren't actually part of this bug, so it's
cleaner to separate the two commits.
