Not on my systems! [Solaris, NetBSD, Windows 98]. I believe it should
open the help for paste().
The point is that it requires a syntactically correct statement after
the ? so that the command parses correctly (with ? as a unary
operator), but the result is to provide the help for the first
syntactic element of the parsed expression, *without* evaluating the expression.
