Thank you for sharing. One problem is that I can't find a suitable completion style for this that would match on substrings, e.g. "pu re" to match "git pull --rebase". The style ‘flex’ is too lax and matches characters anywhere. The style ‘substring’ is the closest, but it requires moving point to the middle of the string. Maybe a new style ‘substrings’ is needed that would match words separated by space as substrings. Also maybe another style ‘initial-substrings’ that does the same, but only matches word beginnings.
