[tor-commits] [tor/master] Fix/suppress shellcheck warnings in git-push-all.sh

[asn@xxxxxxxxxxxxxx]

commit ca667b9a8a654703b26e666d197e1f093eff2e89
Author: Nick Mathewson <nickm@xxxxxxxxxxxxxx>
Date:   Mon Aug 26 09:58:38 2019 -0400

    Fix/suppress shellcheck warnings in git-push-all.sh
    
    (I've chosen to suppress some instances rather than 'fix' them,
    since the fix would require arrays or major refactoring.)
    
    Fixes bug 31519; bug not in any released Tor.
