	usr.bin/ftp    : extern.h ftp.1 ftp.c main.c 

Log message:
implement a `keep-alive' option that sends bytes over an inactive
connection. The FTP protocol provides us with a NOOP operation that
is perfectly suitable for that, and so far servers are happy with it.
Sending the command slowly is an idea I borrowed from spamd.
No change for people not using the option, so it can't break normal ftp.

okay beck@, jmc@
