(cherry picked from commit df8ac05e24)
Move nbdkit-null-plugin to the nbdkit-server package
This plugin is required for probing the presence of filters (see
nbdkit-probing(1) man page), so it makes sense to always have it
around. The null plugin is only 16K in size so it does not add
significantly to the nbdkit-server package.
(cherry picked from commit 048b8de83c)
Consistent use of whitespace
Remove double line whitespace between %package and %description.
Also remove whitespace lines within %package sections.
Double line whitespace is kept between subpackages for visual clarity.
