} Maybe the point is simply it's got limited application, since unless
} it's going into an eval the extra quotes aren't all that useful,
Maybe the point is that :q is a csh-ism, and that result is nothing like
what csh would produce.
In the old days before people worried about 8-bit characters, :q in csh
simply set the high-order bit of every character in the variable value.
Then those high bits would get stripped off again after all the other
substitutions were applied. Thus there was no user-visible change to
the string.
That doesn't make it useless, but if we keep it, it belongs in the
section on differences from (t)csh.
