branch: master
commit 42e23674133e881092c05814c6e11224e642f5f8

Commit: Lars Ingebrigtsen <address@hidden>

    Tweak TLS error messaging on closed connections
    
    * src/gnutls.c (emacs_gnutls_handle_error): Demote the normal
    peer-closed-connection "The TLS connection was non-properly
    terminated" message to a lower level so that it isn't shown to
    the user by default.
