[issue14768] os.path.expanduser('~/a') doesn't works correctly when HOME is '/'

[Bradley Froehle]

New submission from Bradley Froehle <brad.froehle at gmail.com>:

When $HOME=/, os.path.expanduser('~/a') returns '//a' rather than '/a'.

This regression was created by a partially incorrect resolution to issue #5471, and affects versions 2.7 and 3.2 (at least).

$ HOME=/ python2.7 -c "import os; print os.path.expanduser('~/a')"
//a
$ HOME=/ python3.2 -c "import os; print(os.path.expanduser('~/a'))"
//a

In each case the expected result should be '/a'.
