i want an alias (4.3bsd on a microvax, c shell) that will
strip a colon (:) out of the middle of an argument
i.e. 4:15 becomes 415. That's easy to do with echo piped through sed.
what is hard is that i want to use the result as an argument to
expr(1) and capture the output of expr. I'm having trouble with escape
sequences. The colon is, unfortunately, optional, or i could use the "s"
modification of the c shell. Any words of wisdom:

desired version
	mycommand `expr <nocolon> - 5` other args
