The patch adds test-lib.el file for Emacs tests auxiliary stuff. Currently, it implements two functions: `visible-buffer-string' and `visible-buffer-substring'. These are similar to standard counterparts without "visible-" prefix but exclude invisible text. The functions are not used anywhere at the moment but should be useful for testing hiding/showing in the Emacs interface. Edited-by: Carl Worth <cworth@cworth.org> Fixed "basic" test to ignore new test-lib.el file.
