Oh, I see.  That makes sense, then.  It can be done like this, though
it's a bit inefficient; Remind will spin its wheels trying to satisfy
the SATISFY clause after the last lesson.  Luckily, modern computers
are so fast you don't even notice it.

# Count the lesson number starting from date "x"
FSET lesson_num(x) nonomitted(x, trigdate(), "Mon","Tue","Wed","Thu","Fri","Sat")

OMIT 2013-05-19

# 6 lessons, hence "<=6" in SATISFY clause
REM 2013-05-12 *7 AT 18:00 DURATION 1:00 SKIP   \
  SATISFY [lesson_num('2013-05-05') <= 6]         \
  MSG Salsa Level 1 - #[lesson_num('2013-05-05')]
