Completion script $status is visible in a repainted prompt #7555
Description
As reported by @marcusatiliusregulus on gitter:
ive also noticed my promt sometimes redraws (keeping what i typed, but sadly erasing my errorcode output which is annoying). i just dont know what causes this behaviour. i suspect it being related to completions
As it turns out, it is!
> function fish_prompt; echo "[$status]"; end
[0] complete -c foo -a '(true)'
[0] bind \cg repaint
[0] false
[1] foo <TAB><\e><\cg>
# changes the prompt to "[0]"
