Subject: Bug#782692: kmod: spurious spaces in lsmod output

Package: kmod
Version: 18-3
Severity: minor

While using "localyesconfig" to build a custom kernel I noticed that lsmod
output now has trailing spaces when the list of "Used by" modules is empty.

The following (untested but trivial) patch should fix it. It just delays
the space to the point where we are sure that there are more things to print.

Thanks.
