>From my limited understanding of it, I think it would just get too
messy. You'd have to look ahead two tokens: gotta see if the following
token is a '..' (and not '...' or '.314'), then hold onto that while
you check beyond that for a string delimiter. It would be a major hack
(AFAIK), whereas just skipping space between strings falls out of the
existing code with no effort.
