Which readline/history library are you using --- GNU readline, or libedit?
And what version exactly?

FWIW, I do not see this behavior with readline 6.0 on my RHEL6 machine,
nor with the libedit that Apple is shipping in Yosemite (seems to be a
patched copy of libedit 3.0). It wouldn't surprise me a whole lot if it
happens with some other versions of libedit. There isn't a lot we can do
if it's libedit's fault; that library is enough of a mess, and enough of a
moving target, that we have to be satisfied if it works at all, never mind
cosmetic issues.
