Automatically word-wrap the description of extras subpackages 

This only works for package and extra names less than 79 characters long.
I don't expect many actual packages to exceed this limit.
78 characters should be enough for everybody.

Why 78? 79 is the line-lenght limit from rpmlint.
And we need to put punctuation in there.
