Windows 10 CMD prompt now supports "<esc>[xxm" sequences for colors.
Slick "build" window doesn't like this.
I have this env-var set: prompt=$E[91m$p$g$E[0m
In the slick build window, I get a prompt like this:
[91mC:\>[0mcd temp
[91mC:\Temp>[0m
Ugly.
The Slick cmd prompt should support colors, or at least strip out these sequences.
