Um, that's what I thought my original patch did.  Neil was the one
advocating is_nvspace, not me. :-)

My patch does this:

is_space -> ISSPACE
is_hor_space -> ISSPACE && != '\n'

and my reading of safe-ctype vs `ffecom_initialize_char_syntax_' leads
me to believe this preserves the exact same sematics.
