+Subject: [PATCH iproute2] 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.
