Attached patch seems to fix this (needs to be applied in other places in
bash_completion as well), patch forwarded upstream and comments requested.

Potential sample fix
Same problem here with: ssh localh<ESC><ESC>
Patch works for me.
Thanks for testing and the feedback. I haven't heard from upstream, so
committed a patch which changes other similar constructs as well; been running
with it for a while and noticed no problems. This will be in the next Extras push.
