So much for wasting money on standard documents :-) We obviously should unify /bin/sh's echo and /bin/echo. I vote to unify on displaying \c verbatim when -e isn't set, for the reasons I stated in my previous mail. Since bash doesn't recognize \c as special without -e either, I think compatiblity to other platforms is equivalent (bad) for both solutions. If anything, I would rate Linux compatiblity to be slightly more important since we run Linux binaries as well.
