* mod_alias: Ensure Redirect emits HTTP-compliant URLs.

   PR 44020
   trunk patch:
     http://svn.apache.org/viewvc?view=rev&rev=785575
   2.2.x patch:
     http://people.apache.org/~rpluem/patches/foreign_patches/niq_44020.diff
   NOTE: I'm recommending different versions because the trunk
   patch is too strict for a stable line and may "break" broken
   configs thought by their users to be working.
