22617	"Allow to fix translation -> Fix makemessages to not delete debug data and hide errors (and all similar modules using ""msgmerge"")"	Cezary.Wagner	nobody	"Please replace code in make messages to not delete *.po files if error occured and show messages (fix exception later).

Replace this code:
            if errors:
                if status != STATUS_OK:
                    raise CommandError(
                        ""errors happened while running msgmerge\n%s"" % errors)
                elif self.verbosity > 0:
                    self.stdout.write(errors)

With this code (it shows error root cause and save/copy *.po need to solve this error):

            if errors:
                if status != STATUS_OK:
                    self.stdout.write(errors) # bug exception bellow not shows errors
                    import shutil
                    shutil.copyfile(pofile, '%s.debug' % pofile)
                    raise CommandError(
                        ""errors happened while running msgmerge\n%s"" % errors)
                elif self.verbosity > 0:
                    self.stdout.write(errors)

All modules using command line tools should report errors and not delete input if error occured.
