[IPython-dev] fix_frame_records_filenames() messes up Cython tracebacks

In IPython/core/ultratb.py, the fix_frame_records_filenames() tries to
"correct" filenames in tracebacks. However, for tracebacks coming from
Cython, this actually replaces the perfectly fine .pyx source filename
by the compiled .so filename.
So here is a suggestion: in fix_frame_records_filenames(), check that
the better_fn() is not a binary file(*) and only then do the
replacement. This would be easy to implement, any objections?
I am asking this because Sage heavily uses Cython and this is annoying.
(*) the standard way of doing this is to check for \x00 bytes.
