'current' in URLs of mailing list archives not redirecting to 2016-02

[Keith Lindsay]

FYI,

https://gcc.gnu.org/ml/gcc/current/
currently redirects to
https://gcc.gnu.org/ml/gcc/2016-01/
instead of
https://gcc.gnu.org/ml/gcc/2016-02/

Other GCC mailing lists also redirect to 2016-01, instead of 2016-02.
