This can easily lead to an infinite loop, if a variable handler
triggers a repaint and the variable is set in the prompt, e.g. some of
the git variables.
A simple way to reproduce:
function fish_mode_prompt
commandline -f repaint
end
Repainting executes the mode prompt, which triggers a repaint, which
triggers the mode prompt, ....
So we just set a flag and check it.
Fixes #7324.
