Robin Sommer 7344052b50 Changing what's escaped when printing. ... With this patch the model is: - "print" cleans the data so that non-printable characters get escaped. This is not necessarily reversible. - to print in a reversible way, one can go through escape_string(); this escapes backslashes as well to make the decoding non-ambigious. - Logging always escapes similar to escape_string(), making it reversible. Compared to master, we also change the escaping as follows: - We now only escape with "\xXX", no more "^X" or "\0". Exception: backslashes. - We escape backlashes as "\\". - There's no "alternative" output style anymore, i.e., fmt() '%A' qualifier is gone. Baselines in testing/btest are updated, external tests not yet. Addresses BIT-1333.		2015-04-15 16:59:50 -07:00
