Incorrect exit code 0 on failed search

[Ignacio Larrain]

Exit status is 0 even if pattern is not found, due to piping.

Affected commands:
  DEFAULT/none PATTERN list records that match either package or files names
  -S PATTERN list records that match filenames

How to replicate:
$ /usr/bin/dlocate -F /usr/bin/dlocate; echo $?
dlocate: /usr/bin/dlocate
0
$ /usr/bin/dlocate -F /usr/bin/doesnotexist; echo $?
0

Expected result:
$ /usr/bin/dlocate -F /usr/bin/dlocate; echo $?
dlocate: /usr/bin/dlocate
0
$ /usr/bin/dlocate -F /usr/bin/doesnotexist; echo $?
1

I've attached a patch.

FYI, I fixed the bug in Debian with my latest upload 1.02+nmu2.

Cheers,

Someone should fix this Ubuntu bug, I fixed this issue with version 1.02+nmu2 in unstable.
