Re: RCS keyword protection with @w{$} does not work for plaintext

[Karl Berry]

    in the the plaintext document it is literally $Date$ 

Never thought about that.

I'm not sure what can be done either.  It doesn't seem like we should
always make @w{foo} output something like "foo_" or "foo ".  It would
work ok for this case, but @w has other uses.

All I can think of is conditionally defining a macro.

@ifplaintext
@macro dollardate
$_Date$
@end macro
@end ifplaintext
@ifnotplaintext

@macro dollardate
@w{$}Date$
@end macro
@end ifnotplaintext

There must be a better way.
