commit: get rid of ui.backupconfig

This file tests the behavior of run-tests.py itself.

Avoid interference from actual test env:

  $ . "$TESTDIR/helper-runtests.sh"

Smoke test with install
============

  $ run-tests.py $HGTEST_RUN_TESTS_PURE -l
  
  # Ran 0 tests, 0 skipped, 0 warned, 0 failed.

Define a helper to avoid the install step
=============
  $ rt()
  > {
  >     run-tests.py --with-hg=`which hg` "$@"
  > }

error paths

#if symlink
  $ ln -s `which true` hg
  $ run-tests.py --with-hg=./hg
  warning: --with-hg should specify an hg script
  
  # Ran 0 tests, 0 skipped, 0 warned, 0 failed.
  $ rm hg
#endif

#if execbit
  $ touch hg
  $ run-tests.py --with-hg=./hg
  Usage: run-tests.py [options] [tests]
  
  run-tests.py: error: --with-hg must specify an executable hg script
  [2]
  $ rm hg
#endif

an empty test
=======================

  $ touch test-empty.t
  $ rt
  .
  # Ran 1 tests, 0 skipped, 0 warned, 0 failed.
  $ rm test-empty.t

a succesful test
=======================

  $ cat > test-success.t << EOF
  >   $ echo babar
  >   babar
  >   $ echo xyzzy
  >   never*happens (glob) (?)
  >   xyzzy
