Very very rare in *printed* scores produced by programs that
assume a dot means half the value of the note to which it
is appended. That was not true in the Baroque era. A dot
simply meant that the note was longer, but it might be 50%
longer, a third longer, or more than 50% longer (implicit
double-dotting), depending on context. When Bach wrote out
scores, he aligned the sixteenth note after a dotted eighth
with the third note of a triplet of eighths because that's
where he expected the short note to sound. And in several of
his most popular works, he actually had *equal* eighths in
parallel parts (i.e. in parallel with a triplet of eighths
and the dotted-eighth/sixteenth combination); e.g., the
chorale in BWV 147 or Versus 6 in BWV 4. And then there are
the French composers who expected equal notes to be played
inégales. Sigh.
