Ah I've applied only the black color patch, with also the first patch,
everything works fine.

I'm stripping down the escape codes that Zsh/Zle normally produces
managing output. It appears that your setup generates some additional
codes. This should be only a matter of altering // substitution and
sed invocation, but maybe your right, maybe updating zle_highlight /
fg_start_code / fg_end_code is the right way.
