A lot of software uses isspace(3) in places where it feels to me like
isblank(3) would be more appropriate, probably because isblank(3) is
relatively new (C99 and POSIX). I wonder if this is one such place.
It doesn't particularly matter, since the chances of running into one of
the characters that differ is quite remote, but intuitively I would expect
an occurrence of a vertical tab in the middle of a zic.c input file line
to be more likely to be corruption than an intentional whitespace
