PATCH: Allow a value of '\:' in _values

["Bart Schaefer" <schaefer@candle.brasslantern.com>]

The code was checking for backslashes, but counting them as characters for
purposes of the "no multi-letter values" error.  It should ignore exactly
one backslash.

Also, an error of "no multi-letter values" was silly for the empty value.
