Minor fixes.

Starting from this one I won't be touching debian/ directory
since the official maintainer seems to be reasonably quick to
package up things.  The packaging procedure used there seems to
be quite different from what I have, so I'd like to avoid
potential confusion and reduce work by the official maintainer
and myself.
