Currently, unexpected tokens in the parser are shown as the text found, plus the internal token name, including the notorious "unexpected '::' (T_PAAMAYIM_NEKUDOTAYIM)". This commit replaces that with a more user-friendly format, with two main types of token: * Tokens which always represent the same text are shown like 'unexpected token "::"' and 'expected "::"' * Tokens which have variable text are given a user-friendly name, and show like 'unexpected identifier "foo"', and 'expected identifer'. A few tokens have special cases: * unexpected token """ -> unexpected double-quote mark * unexpected quoted string "'foo'" -> unexpected single-quoted string "foo" * unexpected quoted string ""foo"" -> unexpected double-quoted string "foo" * unexpected illegal character "_" -> unexpected character 0xNN (where _ is almost certainly a control character, and NN is the hexadecimal value of the byte) The \ token has a special case in the implementation just to stop bison making a mess of escaping it and it coming out as \\
