Comments with -fpreprocessed


Nathan,

Today I realised that your patch of a couple of weeks ago to disallow
comments with -fpreprocessed means it is impossible to feed a file
into CPP that has been preprocessed with -C.  I don't think this is a
good idea (and was probably the reason I'd not done that originally).

Since what your patch was addressing is not really a problem (CPP
doesn't output comments, except with -C), and if users are editing
preprocessed files in such a way to change the syntax they have larger
problems than inadvertent comments, I think we should revert that
patch.

Do you agree?

Neil.
