tc/lexer: let quotes actually start strings

The lexer will go with the longest match, so previously
the starting double quotes of a string would be swallowed by
the [^ \t\r\n()]+ pattern leaving the user no way to
actually use strings with escape sequences.
Fix this by not allowing this case to start with double
quotes.
