 The problem with a set-subtract function is that it will loose quoting
information if it's used as 'foo `{set-sub ....}', and you thus need to
have it passed variable names to work on. But then you can't just use
this on a command line; you have to build lists beforehand. About
half the time I'd like to use this is on command lines, so I keep
wishing for a better solution.
