003e9442e5 If one's message is longer than the buffer size, then we reset 'cnt' at the 
wrong point and the actual column # get out of sync across the buffer size.

29af67e52c Remove the advertising clause from UCB copyrighted files in usr.bin. This 
is in accordance with the information provided at
ftp://ftp.cs.berkeley.edu/pub/4bsd/README.Impt.License.Change

Also add $FreeBSD$ to a few files to keep svn happy.

a618bd1a15 Perform all trivial ports to utmpx for usr.bin/. 
They were already converted to use libulog, so it's easy to convert them
to utmpx.

149e4bd942 Let wall(1) use utmpx. 
Because our implementation guarantees the strings inside struct utmpx to
be null terminated, we don't need to copy everything out, which makes
the code nicer to read.

Also set WARNS to 6 and add $FreeBSD$ to keep SVN silent.

409fbbd08f Fix some bugs in wall(1): 
- Handle wrapping correctly when \r appears in the input, and don't
  remove the \r from the output.
- For lines longer than 79 characters, don't drop every 80th character.
- Style: Braces around compound while statement.

06cfdceb6c In wall and who, check that the utmp entry isn't stalled, as it is done in w. 
Apparently with the new pts code stalled entries are printed, when they are
not with the BSD ptys.

2b3c9b5598 - Move the prototype of ttymsg() into ttymsg.h. syslogd and talkd 
also use this, and they shouldn't have to have their own prototypes.

- Silence warnings about constness and signedness in ttymsg().  This
  includes changing the return value to a `const char *', and changing
  the types of `left' and `wret' (both byte counts) to ssize_t.

d4edaae88f Instead of printing '(null)' if there is no tty, print 'no tty'. 
In the case where the program is executed by a daemon running in the
background the terminal might not have a tty. The '(null)' is confusing.

Increase the size of a number of buffers and replace strcpy/strcat/sprintf
    with snprintf().  There was a minor and possibly not exploitable security
    hole related to one sprintf().
