By using `token_descr`, as is done for many other errors, we can get slightly better descriptions in error messages, e.g. "macro expansion ignores token `let` and any following" becomes "macro expansion ignores keyword `let` and any tokens following". This will be more important once invisible delimiters start being mentioned in error messages -- without this commit, that leads to error messages such as "error at ``" because invisible delimiters are pretty printed as an empty string.
