escape sequences don't work on terminal output

[noelbush-xx]

When running Behave in Gnome Terminal (the standard terminal in Ubuntu), or in xterm, the escape sequence for "up" doesn't display right. Instead, it looks like:

Scenario: run a simple test # example.feature:3
Given we have behave installed # steps/example.py:3
�[#1A Given we have behave installed # steps/example.py:3
When we implement a test # steps/example.py:7
�[#1A When we implement a test # steps/example.py:7
Then behave will test it for us! # steps/example.py:11
�[#1A Then behave will test it for us! # steps/example.py:11

(Before the "[" there is one of those numbered/boxy symbols indicating a control character, but that doesn't copy/paste properly, of course.)

In "screen" or rxvt, the terminal output is right (the "grey" line is replaced by the "green" line when the step passes). So obviously this is an issue with differences in escape sequences between terminals.

I've looked around to try to figure out how to redefine this "up" command (it's cuu or cuu1) on my terminal, but I can't figure it out. And of course I don't really want to switch terminals just to use behave. Any ideas how to address this?

The ANSI escape sequence for "up" should be correct (AFAIK).
I expect the terminal setting may be wrong. Check the TERM environment variable (and so).
NOTE: I works fine for me under MACOSX with TERM=xterm-256color (default settings).

WORKAROUND:
If this behavior annoys you, switch off coloring for now or use the plain formatter (has no coloring).

I am looking into this issue for Windows.
Because colorama (that could be used for coloring under Windows) does not translate the "up" sequence to the CMD shell.

Well, I submitted a little tiny pull request that fixes this for me, and also works in a few other terminals I tried.

I would like to keep the pretty coloring -- it's nice.

This same problem happens for all my co-workers. So I wonder what terminal you are using -- must be something rather unusual/exotic.

If the change I submitted (just removing a "#") does not break the behavior for you, then it would be nice if you could incorporate it.

I've applied @noelbush's pull request. Thanks!
