run-tests: don't error when glob matched line ends with backslash

As part of writing another test, I triggered an array index error in
glob match processing code by having a (glob) line end in a single
backslash (which is the escape character).

Adding a simple bounds check prevents the error in run-tests.py.

  $ hg init

  $ $PYTHON -c 'file("a", "wb").write("confuse str.splitlines\nembedded\rnewline\n")'
  $ hg ci -Ama -d '1 0'
