We have here a command, "redo", which takes all its arguments and
concatenates them together and allows you to edit the resulting string
with things like ^W ^U  horisontal arrow keys and similar
screen editor type functions. It has an insert mode and an overstrike
mode and so on. So what, you say. Well, if you alias:

    alias r redo \'\!-1\'

in your .cshrc, then when you make a typing mistake, just type

    r

and you can interactively fix it. UNLESS the command you incorrectly
typed had single quotes in it. There should be a way within the csh
history mechanism to get a previous command as a single word without
further interpretation.
