commit e465d9e19087ab150f7e31f21c09e4a147b93b36
Author: Ludovic Courtès <l...@gnu.org>
Date:   Tue Sep 20 17:51:39 2016 +0900

    ui: Do not shadow '_' where it's used as a literal syntax match.
    
    Fixes compilation with Guile 2.1.
    Reported by Mu Lei.
    
    * guix/ui.scm (report-load-error)
    (warn-about-load-error, read/eval-package-expression): Use 'rest'
    instead of '_' as the pattern variable name.
    * gnu/packages.scm (%find-package): Likewise.
    * guix/scripts/build.scm (transform-package-inputs): Likewise.
    * guix/scripts/hash.scm (guix-hash): Likewise.
    * guix/scripts/import/gnu.scm (%options, guix-import-gnu): Likewise.
    * guix/scripts/import/nix.scm (guix-import-nix): Likewise.
    * guix/scripts/offload.scm (build-machines): Likewise.
    * guix/scripts/refresh.scm (%options): Likewise.
    * guix/scripts/substitute.scm (narinfo-signature->canonical-sexp):
    Likewise.
