Title: Don't treat compilation-start timestamp as matching file

compilation-start adds timestamp like 'Ack started at Thu Mar 15 18:17:26' to beginning of compilation buffer. It's recognized as a matching file named 'Ack started at Thu Mar 15 18'. First invocation of 'next-error' results in error, as there is no such file.

Not sure that fixing by enabling column numbers for everyone is the right thing, but at least it works.
