Subject: [PATCH] Make the statschannel system test portable

The usage of the newline in the replacement part of the 'sed' call
works in GNU systems, but not in OpenBSD. Use 'awk' instead.

Also use the extended syntax of regular expressions for 'grep', which
is similarly more portable across the supported systems.
