1. emacs -Q
2. Record a macro like so (starting with <f3> and ending with <f4>):

C-u <f3> ;; kmacro-start-macro-or-insert-counter
SPC ;; self-insert-command
<f3> ;; kmacro-start-macro-or-insert-counter
RET ;; newline

3. Press <f4> multiple times.

Expected:

0 0
1 1
2 2
3 3
4 4
5 5
6 6

Got:

0 0

Indeed, the doc string could use an improvement, and in particular,
using "previous" was misleading.  I've now clarified the doc strings,
and made a point of using "current value" in all places, instead ofg
sometimes using "previous".

One comment about what's been said by Phil:

Actually, the value of the counter is documented to be initialized to
zero before defining the macro, so it's non "undefined" at this stage.

Thanks, I'm closing the bug report.
