Okay. There's other things like correction that also work better with
suffix aliases being separate so I agree that's best.

I've just been trying them out. All looks good. A couple of the whence
outputs are not quite right by the way:
% alias -s c=nedit
% whence -v t.c
c is a suffix alias fornedit  (missing space)
% whence -c t.c
c: suffix  aliased to nedit   (two spaces after `suffix')

I'm not particularly bothered but any thoughts on the suggestion of
suffix aliases checking for files in a special path and not needing the
suffix to be typed? This is closer to what 4DOS did; I'd be slightly
inclined towards not having the current directory in that path and it
could be useful for things like wine and java.

You mean trying to output existing aliases right.

Was probably just laziness when _alias was written. Easy enough though.
