-# push --atomic is the default when TOR_PUSH_DELAY=0, and for release branches.

+#          -s: push branches whose tips match upstream maint, release, or
+#              master branches. The default is to skip these branches. Use
+#              -s when testing for CI environment failures with old code.
+#          --: pass any other arguments to git, rather than the script.
