we are dealing with the issue in the last version of the patch, and that
was the main issue reported and that took a while to get addressed :)

No, unfortunately there is not a standard way to deal with it.  Last

middle of a color sequence) would leave the terminal in a funny state.

Thanks,
Giuseppe
