Author: ed Date: Wed Aug 19 14:30:46 2009 New Revision: 196378 URL: http://svn.freebsd.org/changeset/base/196378 Log: Small changes to the warning message generated by pty(4): - Only print the warning once, instead of filling up the screen. - Use the word "legacy" for the pty_warningcnt description, to prevent confusion. - Use log() instead of printf().
