[en] *Low and behold* → "Lo and behold"

An easy rule to add in English would be to detect the error low and behold (meant to be “lo and behold”).
I don’t think that there would be false positives, but a native speaker should check.

See: lo and behold - Wiktionary

@Dominique_PELLE, thank you for this excellent suggestion! This kind of rule proposal is best posted as an issue on GitHub.

Would you be so kind as to make this into an issue there?
