I suppose that without the existence of pdftex we would do obvious
things, like swimming in the lake in summer instead of sitting in
front of a computer...

Yes, Thanh worked recently on letterspacing, I don't expect that the
2005 manual is up-to-date.

I'm not sure whether it's possible to provide letterspacing on macro
level at all.  Try this:

A\kern0pt V\par

It seems that if you add \kern, you loose the kerning info provided by
the font.  Hence, I think that Thanh's primitive solves this problem.

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
