In some versions of UNIX you have a 32-character limit on the interpreter
comment, which is rather kathedralgic.  With so few characters available,
why waste one of them on a non-informative space?  For /bin/sh, no
problem, but when the program you really want is /usr/local/oursite/bin/sc2.6
you want all the help you can get.  Has that limit gone in 4.3BSD?  If not,
will it go in 4.4?  What about V.4?
