When installing a module with cpan, the resulting tests expect a
real ANSI terminal and the interactive shell mode is not.
As a result the ^M that should wrap to the begining of the
line is printed and the next test output is appended
instead of replacing the previous one.
As a result,the buffer is littered with tests results.
The good news is that there is some hook to do filtering. It is used by M-x ansi-color-for-comint-mode-on which looks fine. Has someone written a filter that does the right thing with ^M. It should be easy to write for a elisp master but I am just a elisp hater. Help! A second look shows that to be perfect one should implement one of the ANSI cursor move. -- stefp In reply to problem: emacs interactive shell and cpan by stefp
