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.
