bug#55234: 28.1; replace-string in rectangle regio

I thought that the implementation of region-beginning could be:

  (mapcar 'car (region-bounds))

or better for backward-compatibility:

  (caar (region-bounds))

and region-end:

  (cdar (last (region-bounds)))

Please try these on the original bug report - they completely fix the problem.

Isn't this a workaround?

PS: I'll reply to your other posts after more testing of search/replace 
problems.
