  1. perf: calculate anzu count faster and with less memory 

    Instead of allocating a list with N items and returning its length, just
keep a tally of the number directly. This can also avoid generating lots
of garbage that has to be collected.

The performance impact can be tested with this:

  (benchmark-run 10 ; or some other number of repetitions
    (let ((last-kbd-macro [?/ ?. return]))
      (call-last-kbd-macro)))
