Ronald Oussoren 9f20d9d0ee Issue 6877: this patch makes it possible to link the readline extension
to the libedit emulation of the readline API on OSX 10.5 or later.

This also adds a minimal testsuite for readline to check that the
history manipuation functions have the same interface with both
C libraries.

"""
Very minimal unittests for parts of the readline module.
These tests were added to check that the libedit emulation on OSX and
the "real" readline have the same interface for history manipulation. That's
why the tests cover only a small subset of the interface.
