That message is a reflection of where things currently are. It contains a
patch that will allow bash-completion to work unchanged. (In a nutshell,
bash-completion makes assumptions about what compgen will do with quoted
null arguments that changed between bash-4.2 and bash-4.3.)
I think that patch will fix most, if not all, of the bash-completion
problems. I need people to test it, since the platforms I commonly use
for development (Mac OS X, RHEL) do not install bash-completion.
For instance, I believe that the problem with these unquoted special
characters is that they break words for readline, and readline passes
an empty argument to the completion function as the word to be completed.
I'm not sure what bash-completion does with that to make it include the
previous word.
