Hello!

I have been working on blog posts about keyboard macros and found that
it would be useful to have comparison functions for the keyboard macro
counter.

I implemented two functions to load and save macro counter values from
and to number registers; three comparison functions of the macro counter
with a number register that conditionally increment the counter; three
comparison functions of the macro counter with a prefix that terminate
the macro execution. This simplifies handling multiple counters and
conditional macro termination.

I am attaching the changes to:
  emacs.texi
  kmacro.texi
  NEWS
  kmacro.el
  kmacro-tests.el

I hope this functionality is useful and that I followed the coding and
style standards.

Thanks!
