It might be a good idea to make it available as an option.  Probably
not as "the way it is done", because everyone who's gotten used to the
other way will scream.

Seems like an argument for a good editing shell, like ksh, tcsh, or
mcsh (my own variant, incompatible with all the others and (-: of
course much better than any of them :-)).  I'd type
ESC b ESC b ESC b ESC b ESC b ^D s
and it'd be all fixed.

Actually, this is an argument for putting full-fledged line editing
into the tty driver (because people don't make mistakes only when
typing to the shell).  But given the current architecture of the
kernel, this is difficult to do right.  I guess it's time to redo the
kernel.  Hmm, this project is getting bigger!
