Adding @Johannes Schindelin to the loop.

Thanks for your investigation so far.

So how do we proceed, assuming MSYS project does want to use the
installed readline? I checked the readline PKGBUILD, and it only has
very basic patches, none of them looks suspicious.

Is (external) readline not used in cygwin/bash?

Do you suggest that there's a bug in readline, that your change in the
runtime uncovered? Or is it the other way around?

What might we break if we revert the part I referenced earlier in
fhandler_tty.cc?
