[cvsnt] Commit continues after non-zero status from verifymsg

[Haasjes, Klaas]

It is a bug in logmsg.cpp, introduced somewhere after 2.0.58d, when the trigger activation code is completely rewritten.
The call to the verifymsg script is moved to the function verifymsg_proc, but this function always returns 0. Besides that, the return status of the call to verifymsg_proc in function do_verify is not tested, so verifymsg always succeeds.

After making the following changes in logmsg.cpp (build 2.5.01.1976), it works like in 2.0.58d:
in do_verify, replace line 475: run_trigger(&args,verifymsg_proc) by:
			if (run_trigger(&args,verifymsg_proc)) {
				/* Since following error() exits, delete the temp file
				now.  */
				if (unlink_file (fname) < 0)
					error (0, errno, "cannot remove %s", fname);

				error (1, 0, "Message verification failed");

			}

in verifymsg_proc replace line 672:
	return 0;
by
	return ret;
