branch: feature/gnus-select
commit 23fb2521f43f842d0c9d5877580accc83ce3d9c4
Author: Michael Albinus <address@hidden>
Commit: Andrew G Cohen <address@hidden>

    Optimize "make check" and "make check-maybe"
    
    * lisp/emacs-lisp/ert.el (ert-run-tests-batch): Print summary duration.
    
    * test/Makefile.in (TEST_LOAD_EL): Set default to "no" for
    targets all, check, and check-maybe.  (Bug#30807)
    
    * test/README: Reflect recent changes in Makefile.
    
    * test/lisp/net/tramp-archive-tests.el
    (tramp-archive-test99-libarchive-tests): Tag it :unstable.
