Hi,

In lexer.ll, there is some code that checks the version specified in the .ly file against a hard-coded variable oldest-version and issues a warning (well, a non-fatal error message) that the file needs to be updated. However, "oldest-version" has been set to 2.7.38 since 2006 or so. Perhaps we haven't had any drastic grammar changes since then, but wouldn't it still make sense to at least issue a warning if you for example run a 2.16 file in 2.18? Hopefully, this would reduce the number of emails where the answer is "did you run convert-ly?".
