Agreed.  "foo\.bar" will match "foolbar" as well, but 'foo\.bar' only
matches "foo.bar".  The advantage of single quotes is that you're not
escaping the escape characters with themselves; what's inside the
quotes is simple RE syntax, so you only need to think about one of the
layers at a time.

Either approach works, of course.
