Bug 703549

Description of problem:
The mtr tool has multiple output options available.  Aside from the normal "interactive" mode, there is also a report mode available that will run for a certain number of cycles and then quit and output the results to the screen.

There is also an option for wide report mode (in both the man page and --help output), but this seems to be ignored and runs the same as interactive mode, updating the screen after each cycle.  At the end of the output, the screen is cleared and output is unavailable to review.


Version-Release number of selected component (if applicable):
sh-4.2$ rpm -q mtr
mtr-0.80-3.fc15.i686
sh-4.2$ mtr --version
mtr 0.80
sh-4.2$


How reproducible:
Every time.


Steps to Reproduce:
1. run mtr with -w (or --report-wide) to not truncate hostnames and -c to specify a number of cycles
2. look at output on screen during and after run completes

  
Actual results:
The output from mtr displays incrementally for each cycle and is cleared off the screen and unavailable when you are returned to a prompt.


Expected results:
The output from the run should be visible on the screen (for parsing, cutting and pasting, etc) when you are returned to a prompt and the screen should not display results (and re-draw results) after each cycle.


Additional info:
When run in report mode normally, there is no output displayed on the screen until the run finishes and the summary prints.  It seems that wide mode should behave almost identically and just have a wider field for hostname.  As it currently stands, the switch appears to be ignored and the mtr runs the same as when the switch isn't supplied...this makes redirecting to a file to capture output kind of worthless (because of all the control characters), not to mention the output doesn't remain on the screen afterwards to parse.
