Glad I red this thread before replying to the other one dealing with the
same issue.
I once worked on an issue on ksh93 regarding printf discrepency vs libc
printf, and got replied that "ksh is not C". I Think we got to admit that
shell's printf have departed from libc since long and now if a feature in
libc appears and collide with printf(1) then we got to get yet another %
exception char. In bash docco I see %b %q and %(datefmt...), so for a new
feature we should get something that we think libc as little chance to
target.
My vote is for posix_printf %B mapping to libc_printf %b, with the idea
that libc has little chance to have %B meaning UPPERCASE BINARY :-), as %x
%X do.
And yet one more line in the docco explaining this divergence.
