Hmm. I like that idea: have the shell *not* interpolate things by
default, unless you explicitly say to do so. So by default typing:

	rm *.txt

will pass "*.txt" to rm as a single argument, whereas:

	# Not real syntax:
	rm `*.txt`

will expand "*.txt" as a glob and pass the result to rm.

Yeah I agree with that one. Unfortunately I don't think it can tell,
because the previous command writes to stdout directly (it doesn't go
through bash -- else it's be too inefficient, you'd have processes
copying stuff from each other all over the place). The terminal doesn't
let you ask "what was the last char sent to you?".

Having said that, though, the terminal *does* have an escape sequences
(yeah, ugh) that bash *could* use to find out where the cursor is, and
if it's not at column 0, insert a newline.

Unfortunately, us old hands have gotten so used to this misbehaviour
that we actually *use* it to detect whether something has a newline at
the end or not. Another of those historical accidents calcified before
it can be disinfected.
