No colours but escape chars in case of HTTP tracing

[mdeknowis]

Hello,

we are creating our own bx plugin. We use the Http logging according
https://github.com/IBM-Cloud/ibm-cloud-cli-sdk/blob/master/docs/plugin_developer_guide.md#41-http-tracing

But we realized, that instead of colors, we see escaped control bytes.
The normal logging coloring is working (Warn, Fatal...)

What's your platform? Was the plugin running on a real terminal?

Hello,

I was running it in Windows Shell (cmd). Funny, it's working now:

But instead of the control characters, there are just no colors. I don't know, if this is by purpose.

In general colors are working:

Please close this, if no colors should appear.

@mdeknowis no, it's not by purpose... We will check the code, thanks for reporting the issue.
