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.
