75ac3edf1d Remove hand-written version of strcspn(). 
The code searches for the first occurence of @, : or !. Upon failure, it
returns the index of \0. This is exactly what strcspn() does.

b6d9e1f355 ANSIfy function prototypes. While I am there, constify some parameters and 
make use of C99 sparse initialization for static variables, this makes talk(1)
to compile cleanly with WARNS=6.

9d61853d9f Change the default behaviour of talk(1) to use "localhost" as the 
"machine name" in ntalkd(8) request packets, when the destination
and source are local.

This should make talk(1) use much more pleasant for those security-
conscious individuals who have chosen to bind talkd to "localhost".

Previous to this change, talk(1) would require that the hostname of
the machine, as retrieved by gethostname(3), resolved to a valid and
reachable IPv4 address, using gethostbyname(3).

This makes talk(1) dependent on a valid host entry for "localhost"
in /etc/hosts (or the Domain Name System).

add usage().

285926046a Make talk automagically find out the interface IP address where the 
remote peer will be connected through.  This avoids the ``Checking for
invitation on caller's machine'' problem for multi-homed hosts.

Thanks to: Garrett, for his `find_interface' example

c6189102a3 Partially back out previous fix (in cases ':' and '!'), 
leave case '.' as valid user name, not host reference.
Document new behaviour.

016d299205 Remove undocumented talk behaviour, when names like 
aa.bb aa:bb and aa!bb treated as user+host and not as local user
names (especially aa.bb is common case).
Only @ is valid user/host separator according to manpage.
