apt-cache's return code should be != 0 if source package could not be found

[Daniel Holbach]

daniel@daydream:~$ apt-cache show gedit> /dev/null; echo $?
0
daniel@daydream:~$ apt-cache showsrc gedit> /dev/null; echo $?
0

daniel@daydream:~$ LC_ALL=C apt-cache show gedita> /dev/null; echo $?
E: No packages found
100
daniel@daydream:~$ LC_ALL=C apt-cache showsrc gedita> /dev/null; echo $?
W: Unable to locate package gedita
0

Maybe it should return 100 as well for a non-existing source package.

Apparently sbuild seems to rely on this return code....
