That -r was never meant to stay. It's still undocumented and I
don't expect anyone ever used it. I only just found out when
digging up that old discussion.

Having said that, it's not really incompatible with ksh's print.
With -f, -r (for raw; an option you want to use most of the
time like for the read utility) is ignored like for many other
options, like it was in zsh before that change.

$ print -f '%b\n' '\\\\'
\\
$ print -rf '%b\n' '\\\\'
\\
$ print -f '%s\n' '\\\\'
\\\\
$ print -rf '%s\n' '\\\\'
\\\\

$ print '\\\\'
\\
$ print -r '\\\\'
\\\\

In any case, printf and print are separate utilities (only
printf standard), they don't have to support the same set of
options.

-1 (one, not L) may be a better name for it.

Or -B <n> to specify the maximum number of batches (passes; -b,
-p, -P are already taken with zsh's print).

BTW, ksh93's printf / print -f seem to be pretty buggy wherever
%x$b is involved at least:

$ print -f '%1$s %1$b\n' '\\\\'
\\\\ b
$ print -f '%1$b %1$s\n' '\\\\'
\\ \\
$ printf '%1$b %1$s\n' '\\\\'
\\ \\
$ printf '%1$s %1$b\n' '\\\\'
\\\\ b
