[Groff] gropdf track kerning issue

[Peter Schaffter]

Deri,

I've encountered a problem with gropdf and the .tkf request.  When
I process this example with -Tpdf, the first block of type renders
perfectly.  However, when I add track kerning, two anomalies creep
in: extra space is being added between the "D" and the en-dash
afterwards (in the \*[D-] string), and the letters "n" and "v" in
"conversation" are overprinting (see attached .pdf).

Following Day 40, the arrangement of the hieroglyphs began
to look like dialogue.  First, there'd be a stanza headed \*[JWS-].
Afterwards came two more blocks, the first one introduced by \*[D-].
A con\%versation between minds?
