I wondered if there was any interest in incorporating Raphaël Droz's patches to add colour to tab suggestions, like the colour listings from 'ls --color'. It would seem like a simple and useful feature to have (and is said to exist already in other shells like zsh and fish).
The patches are at http://gitorious.org/drzraf/bash/commits/enhanced-completion (patches 1/6 to 8/6). I have applied these patches to the bash-4.2 source and successfully built a version with colour support. The original emails about the patches can be read at http://www.mail-archive.com/bug-bash@gnu.org/msg09296.html (or see email with X-Message-Id: 20110530233242.ga9...@b1b1.lan).
