[gnu.emacs] sugestion for dired feature

djm@ENG.UMD.EDU (Randall S. Winchester) (02/23/90)

One feature I would find really handy in dired is a command to diff
two files against each other (maybe the ones at point and mark).  One
thing this would be handy for is comparing two backup files to decide
whether to delete one or both of them, but of course it would have
lots of other uses.  Perhaps if this command were given an arg it
would produce a context diff.
