a quick recursive grep shows:

coreutils/tr.c
coreutils/printf.c
e2fsprogs/fsck.c
editors/awk.c
libbb/bb_echo.c
loginutils/getty.c
shell/cmdedit.c
shell/lash.c

no argument there.  notice i *didn't* say that this conditional had no
value.  what i said was that it has little value if it's implemented
by hardcoding it in the source file.  if it really deserves to be a
choice, then its selection should be moved to the config menu, that's
all.

perhaps this feature should be made part of a larger class of
"non-SUSv3" thingies.  or however that would work.
