A possibly useful tip (for those who hate back-slashes): Instead of
backslash-escaping a space in a ?:x regex, you can also use "[ ]" (i.e., a
single-character character class containing just a space. Personally, I find it
easier to read.
Also, when I find myself putting a space character in a pattern, I usually stop
and ask myself, "Would a \s make more sense (or just as much sense) here?
