As they should be!  This is the very reason Real Programmers never
comment their code!

True, but hardly the only one in pdfpic.tmac.  And like long names,
.shift, and .break (three groffisms I noticed at first glance), \R is
also implemented in at least Heirloom.

That'd be best, but seems further off, whereas a sed tweak to emit a
single line of two \R escapes (I never use this feature, so I had
actually forgotten it existed) is simple enough to, if not make it
into 1.23 itself, at least be in a 1.23.1 minor release, if such a
thing happens.
