That matches an entire line which is just a string of 'word'
characters ( A-Z, a-z, 0-9, and underscore ).

Well, it doesn't seem a very interesting thing to want to do, but I
think you mean:
/^\w[\w\s]*\w$/
which matches an entire line consisting of word characters or
whitespace,
with no leading or trailing whitespace. Is that what you wanted?
One restriction - the least thing it'll match is two word characters. If
you
want a single-character line to match do this:
/^\w(?:[\w\s]*\w)?$/
which still won't match an empty line. Do you need that too?
Cheers,
