Seriously? Is this what I think it is: that csh tromboned out characters

typed it?

I think so.  The key here is that csh does not implement a command
line editor.  It relies on the cooked mode processing of the standard
tty line discipline.  It needs to feed the expansion results in
there as if they had been typed, so actions like character/word/line
erase can be performed.

Wow, ... I see considering only csh *programming* to be harmful was
an overly optimistic view.

static char *sccsid = "@(#)file.c 1.1 (Berkeley from Hp Labs) 11/02/83";
