Subject: [PATCH] Removed awk regexp character classes. On Debian/Ubuntu, awk
 (mawk 1.3.3 Nov 1996) is not supporting regexp character classes.  See also:
 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=314323

This was causing unit test `_known_hosts_real' to fail.  To run the
test:

    ./run unit/_known_hosts_real.exp
