[guix-commits]

rekado pushed a commit to branch wip-texlive
in repository guix.

commit 6d668a16be4af017aacf8e20ecfa044b84d637d3
Author: Ricardo Wurmus <address@hidden>
Date:   Mon Jul 8 18:34:39 2019 +0200

    build: svn-fetch: Use "svn export".
    
    * guix/build/svn.scm (svn-fetch): Use "svn export" instead of "svn checkout"
    because it does not include the .svn directory and allows us to fetch single
    files.
