Custom Command Level Bash Completion

[altostratous]

I have reviewed recent change logs and #65. AFAIK click has a hardcoded behavior to get command autocompletion options only based on filtering commands which do not start with what the user has typed. Hence the following case-insensitive use case won't be possible (unless you inject the search function to the bash completion module as a workaround):

# Upon pressing double tab after the following
$ click-tool goh
GoHell         GoHere

It would be helpful to have something like autocompletion option mentioned here for Groups as well as options. For example, having a custom search function as a method, or field to be configured for Groups, would be really helpful.

Also, I am really very motivated to contribute to click and will form a PR if you're interested in this feature.
