Comment:
The fix works and makes sense to me (positive review for that). I've added
a doctest (needs review), and rebased the original patch against
4.8.alpha5.
Unfortunately, something is wrong with exceptions at the moment:
{{{
sage: (a*x).complex_roots()
ERROR: An unexpected error occurred while tokenizing input
The following traceback may be corrupted or invalid
The error message is: ('EOF in multi-line statement', (1731, 0))
...
}}}
and that's fixed by Simon King's patch in #11900, so I've added a
dependency there. The milestone update is to match #11900.
