I agree here, /bin/sh is used much more commonly for writing shell
scripts than playing the role of an interactive shell in my experience. Most
of the time, it's tcsh or bash for people who want to hang out in a shell.
To me, adding command editing and history features are about as useful as
adding them to the perl or tcl binaries. I'd much rather have a small, fast
loading script interpreter. Does the POSIX requirement actually say that
there has to be a /bin/sh with all these features? It'd be nicer to have
/bin/sh that's a normal /bin/sh (no job control, no editing, etc...) and
maybe another one (even bash) for people who want to hang out in it.
