Limit special-casing of _ variable to doctests....
Limit special-casing of _ variable to doctests. In doctests, _ *must* be special-cased and removed from the user's namespace because otherwise Python won't set it. But we were doing this special-casing unconditionally, making it impossible to write unittests that checked the _ variable after cell execution. This commit makes the special-casing of _ apply only in the doctest execution (where it's needed) and leaves normal unittests alone.

"""
A backwards compatibility layer for IPython.Shell.
Previously, IPython had an IPython.Shell module. IPython.Shell has been moved
to IPython.core.shell and is being refactored. This new module is provided
for backwards compatability. We strongly encourage everyone to start using
the new code in IPython.core.shell.
