Oh dear. I didn't notice that. print was one of the things which David
Korn was keen to have in the standard and without the -f, ksh's print
would be little more than echo. It's also quite a nice feature.

ksh allows -s, -p and -u to be combined with print -f. What you say
about this precluding it from being a module is certainly true. What I
think I'll do is commit this as it is for now. I also think this could
be safely committed to the stable branch so unless anyone says otherwise
I'll do that. My argument for this being that it doesn't touch any
existing functionality and just does something where we didn't do
anything useful before - so it is similar to us allowing new completion
functions to be added to 4.0.
I'll put the ksh print -f functionality on my todo list though. It makes
sense to combine the -b, -m, -s, -o, -O, -i, -u, -p, -z, -D and -P
options with -f. -r, -R, -n, -l, -N and -c would make no sense to
combine. -l and -N would be fairly redundant because it would be better
to use a format of "%s\n" or "%s\0" so they should perhaps then be
declared obsolete. -P (and maybe -D) is also perhaps slightly
unfortunate because a %P format specification might be better.
