src/bin/ksh/NOTES says:
- pdksh accepts empty command lists for while and for statements,
while at&t ksh (and sh) don't. Eg., pdksh likes
while false ; do done
but ksh88 doesn't like it.
if only i had never read that file! i would have happily stuck to
while :; do

maybe not the only way, but it would work and is completely reasonable.
