Hey Christos,

could I bother you to take a look at this python PR 
<https://github.com/python/cpython/pull/16986>, and the related lldb bug 

The executive summary is that there is an incompatibility between 
readline and its libedit emulation, which python needs to work around. 
Is there any way this can be fixed in libedit?

I guess the presence of the workaround will make the fix tricky, because 
then the workaround will be wrong for the "fixed" libedit, but it's 
still probably worth it to try to resolve this somehow.
