Add command line option to pause output on failure about googletest HOT 1 CLOSED

We'd like to keep gtest simple.

There are several alternative ways to get what you want (or something
close):

- set the console window buffer size to a larger value such that you
  can scroll back to see the entire test output.

- use a continuous build system that can display the XML report
  generated by gtst (e.g. Hudson).

- pipe the test output to 'less' (or 'more' on Windows).

- redirect the test output to a file and read it later.

- run the test inside Emacs.

- run the test in an IDE (e.g. Visual Studio).

- (when the event listner API is published) implement a custom output
  printer that can pause on failure.

Therefore we'd like to avoid a new command line flag.
