[Ludovic Courtès]

civodul pushed a commit to branch master
in repository guix.

commit 637cd1254320fd89fe6d910b3fa7665b19487072
Author: Ludovic Courtès <address@hidden>
Date:   Wed Mar 2 14:42:39 2016 +0100

    graph: Ignore 'GUIX_BUILD_OPTIONS'.
    
    Previously 'GUIX_BUILD_OPTIONS' would be honored, but 'guix graph' does
    not support the common build options.
    
    * guix/scripts/graph.scm (guix-graph): Use 'args-fold*' instead of
    'parse-command-line'.
