Allow RegEx matches of length 0. This seems more correct to me. (However, this is not super important in practice. Grammar files should not contain regular expressions that could match the empty string; if such a RegEx matched 0 characters once, it would match again and again forever, since it wouldn't consume any input.)

Fix what looks like an off-by-one error in RegEx::longestMatch()'s lastMatch calculation, and a corresponding +1 in code using longestMatch, and add a test.

Fix a minor bug in the lexer (it would not match the last character of the input) and add Lexer tests.

Use std::string::substr() instead of adding one character at a time. This patch also removes a few unused util functions that are easily written using substr().

Remove one unnecessary backslash-check in StringReader::getTokens(). (This patch looks like it's removing the last backslash-counting loop, but really it removes the first one and then reindents everything.)

Replace some code in StringReader::getTokens() with std::string::find_first_of(). Since this makes found_pos unsigned, a few comparisons involving found_pos must be adjusted (unsigned integers are always >= 0).
