[docs] [issue11643] Use |version| instead of X.Y in the doc

Ezio Melotti added the comment: I fixed the one in site.py. If there's no way to use |version| in :file:`...` I think using {X.Y} is OK, so that can be done where a bare X.Y (without {}) is currently used. ---------- _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue11643> _______________________________________
