commit 46993cd3846a8c8935c980e30bbc3718338e2378
Author: Panu Matilainen <pmatilai@redhat.com>
Date:   Fri May 9 10:56:46 2014 +0300

    Sometimes a smaller hammer is better (but only sometimes)
    
    - The sed-munger added in commit ccd6281e699781e0b00edb16b6e9f4dec6878c15
      causes bigger breakage than it fixes, perhaps because the hammer
      applied was disproportionally large. The only thing needing adjustment
      is ${prefix} in case when localstatedir is not explicitly set, so
      we fixup just that instead of "everything".
    - Discovered via RhBug:921973 testing
