Description of problem:
RHEL6 wall command's man-page says that the length of the message
is limited to 20 lines, but it should be 22. 

-RHEL6 wall man-
<snip>
      The length of the message is limited to 20 lines.  For every invocation of
      wall a notification will be written to syslog, with facility LOG_USER  and
      level LOG_INFO.
<snip>

-RHEL5 wall man--
<snip>
      The length of the message is limited to 22 lines.  For every invocation of
      wall a notification will be written to syslog, with facility LOG_USER  and
      level LOG_INFO.
 <snip>

wall.c has not been changed since RHEL5, but RHEL6 man page has been updated like the above.

RHEL6 syslog:
Jul 30 11:56:32 localhost wall[2878]: wall: user root broadcasted 22 lines (79 chars)

This also indicates that RHEL 6 wall can process up to 22 lines.

corresponding source code:
<snip>
     95   i = 0;
     96   for (p = buf; *p; p++) {
     97         if (*p == '\n' && i++ > MAXLINES) {
     98                 *++p = 0;
     99                 break;
    100         }
    101   }
    102 
    103   openlog("wall", LOG_PID, LOG_USER);
    104   syslog(LOG_INFO, "wall: user %s broadcasted %d lines (%d chars)",
    105         whoami, i, strlen(buf));
