How about 't'?
I do realize there'd be a problem with hooks, which use 't' as a flag
in a list of functions...
Of course, there's an unfortunate tradition in computing to consider
1, rather than infinity, the canonical "true" value, so (t nil) might
be expected to be nil, but apart from that, I don't think confusion is
that likely, at least with a single argument.
