Bug#4349: dpkg-source has misleading warning message

[Owen Dunn <owen@greenend.org.uk>]

Package: dpkg
Version: 1.3.9

sfere:~$ dpkg-source -b procmeter-2.0 procmeter-2.0.orig.tar.gz
dpkg-source: warning: .orig.tar.gz name procmeter-2.0.orig.tar.gz is not <package>-<upstreamversion>.orig.tar.gz (wanted procmeter_2.0.orig.tar.gz)

This should read `... is not <package>_<upstreamversion>.orig.tar.gz
...'
