PR mi/14270 points out that mi-break.exp has some tests for an unimplemented "-r" switch for "-break-insert". This switch was never implemented, and is not documented -- though it is mentioned in a comment in the documentation. This patch removes the test and the doc comment. Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=14270
