Looks fine to me.

I am mystified by this. As far as I can see, none of M&S' stuff contains
such a file header---indeed, it seems to be incompatible with the .DOC
style. I should have thought that the header has to be
the FIRST thing in the file, yet it has to be surrounded by \iffalse...\fi
doesn't it?

The other difficulty appears to be that the usefulness of
"\filedate" evaporates
if one then has to explicitly insert the date in the header.

Perhaps I am missing something, but it seems to need some thought.
