New description:
The `sage0` interface doesn't always return exactly the same thing.
At #10528 the apparent problem is solved by making the doctests less
rigid. But the real problem is not fixed there. With the real problem
being that the piece of code:
{{{
sage: sage0.clear('x')
sage: sage0.get('x')
}}}
returns
{{{
"...NameError: name 'x' is not defined"
}}}
in some setups and
{{{
'...NameError: name \'x\' is not defined'
}}}
in other setups.
