Strings may not contain a double quote unless it is escaped. Reference: https://doc.rust-lang.org/reference/tokens.html#string-literals (This will still not colorize multi-line strings with an unescaped newline, will still colorize "this\" as if it were a valid string, and will still miscolor things when there is another string after the closing quote of a two-line string. But those things can't be helped -- line-based regexes cannot emulate a full parser.) This fixes https://savannah.gnu.org/bugs/?61361. Reported-by: Elias Jonsson <e@ejon.eu> Bug existed since version 2.6.1, since the Rust syntax was introduced.
