The patch replaces all (message (buffer-string)) calls in emacs tests with (princ (buffer-string)). This avoids accidentally interpreting '%' as format specifiers and makes code simpler because we do not need to capture stderr. Also, the patch works around an Emacs (23.3+1-1 on current Debian Unstable) segfault in "Ensure that emacs doesn't drop results" test. Note: the segfault does not happen on every test run. Though, it seems to be consistently reproducible if the test uses 300 messages instead of 30. Hopefully, it is the crash described in Emacs bug #8545 [1] which is already fixed.
