Author: jilles Date: Sun Sep 5 21:44:50 2010 New Revision: 212244 URL: http://svn.freebsd.org/changeset/base/212244 Log: printf(1): Clarify that \OOO produces a byte, different %b escape sequences. Octal escape sequences are expanded to bytes, not characters, and multiple are required for a multibyte character. The valid escape sequences in %b strings are slightly different from the escape sequences in the format string.
