My guess is that the space is there specifically to prevent rpm from
interpreting the %define macro (simply # commenting doesn't prevent it).
Yup. Originally, I think it was a # replacing a %, but at some point,
moved to "#% "... Same difference.
%% is a cleaner way to do it, but some packagers may not realize it
disables the macro.
While %% may be a bit cleaner, a # in front of it makes more sense to
more people I think.
