Hi

Was just going over bug-readline and lkml archives and found no continuation
of this.

There was a patch proposed but didn't get applied.
https://lkml.org/lkml/2013/8/17/31
Maybe it only needs proper patch submission?

Looking from bug-readline archives debugging it took huge amount of work and
would be sad that all that ended up being wasted.

Whole thread if someone lost it https://lkml.org/lkml/2013/7/25/205
