# NOTE: Caches are invalidated (cleared) only in the precmd hook. This means that
# highlighting may not reflect state changes after the last precmd hook. For example,
# if a zle widget or another process deletes /bin/ls while ls is highlighted as a
# command, it'll keep being highlighted that way until the precmd hook is executed.
