cosmetics: rename t/ax/test-runner => t/ax/runtest The latter is shorter and clearer. Better to do the rename early, before other developers or contributors begin to get used to the 'test-runner' name. * t/ax/test-runner.in: Rename ... * t/ax/runtest.in: ... like this. * Makefile.am, t/README, .gitignore: Adjust.
