Bug#717241: month exchanges between russian and russian.ancient

Package: texlive-lang-cyrillic
Version: 2013.20130530-1

When I try to make up simple tex file, that uses russian (modern) localization of babel package (like data.tex in application), latex make file, which contains wrong name of current month (July): іюль (as in russian ancient spelling) instead of июль (modern spelling). Then I try to make up file with russian ancient localization (data.ancient.tex in application) and result were interesting: июль instead іюль.

As I understand, bug is in defenition of \daterussian and \daterussian@ancient for T2* encoding in russianb.ldf file (in /usr/share/texlive/texmf-dist/tex/generic/babel-russian directory).
One of solution looks so:

--- russianb.ldf 2013-07-18 09:46:02.417089664 +0000
+++ russianb.fixed.moth.spelling.ldf 2013-07-18 09:47:14.641092573 +0000
