Enhancing autocompletion

[Removed by request]

I'm using Ubuntu 15.10 dev with bash 4.3-14ubuntu1 and if on autocompleting with tab a path gets only partly completed it is then required to press tab another 2 times to get a list of all targets. But since the user knows already from the partly autocompletion without a trailing space that the path is incomplete I think the next pressing of tab should already show a list of all targets.
