It is somewhat annoying that "git diff gi<TAB>" stops at expanding
it to "git diff git" and then upon another "git diff git<TAB>"
offers tags whose names begin with "git" (e.g. gitgui-0.10.0) but
the pathname git.c is not included in the choices.  My wish was to
take the union in such a fairly limited case.  I tend to agree with
you that "git diff <TAB>" that expands to all refs and pathnames
would be useless, but so is expansion to all pathnames (or refnames
for that matter).

In any case, I wouldn't insist on AI perfection in the first place
;-).  As long as it works reasonably well, I am happy (and I think
the current completion code already works better than reasonably
well, at least for me).

Thanks.
