right.  which i thought included things like:

lim=0
sect[$lim]=main;        alt[$lim]="MAIN";               lim=`expr $lim + 1`
sect[$lim]=tv;          alt[$lim]="TELEVISION";         lim=`expr $lim + 1`

but solaris's /bin/sh doesn't do that, and neither does netbsd's.  the
"well-defined" set of features is blurred by the fact that "everyone
supports it", but everyone also adds their own stuff.  it's hard for
me to tell where it starts and ends.  :(
