An excellent question, and I think I overstepped things. The documentation¹ and answers on Stack Exchange² say "&&" and "||" are logical operators (so the logical symbols work) but "and" and "or" have lower precedence and are used differently.
It'd be best to just prettify "&&" and "||" with symbols, and anyone who wants "and" and "or" could add those by hand. Shall I send a revised patch, or do you just want to delete those bits?
