commit 0af3f404e9f5bd12099c6f63fe5e20e9ed5b029e
Author: Ludovic Courtès <address@hidden>

    build: Ensure man pages are not rebuilt by users.
    
    * doc.am (doc/guix.1): Remove dependency on 'scripts/guix' since every user
      would end up rebuilding 'guix.1'.  Add dependency on guix/scripts/*.scm.
      (doc/guix-daemon.1): For the same reason, depend on 'guix-daemon.cc' 
instead
      of 'guix-daemon'.
      (doc/guix-$(1).1): Similarly, remove dependency on 'scripts/guix' and 
depend
      on 'guix/scripts/$(1).scm' instead of the .go file.
