There was a small fix to completion-setup-function to work with
partial-completion-mode except for in the situation that you
describe.  There remains a comment in the source:

    ;; If partial-completion-mode is on, point might not be after the
    ;; last character in the minibuffer.
    ;; FIXME: This still doesn't work if the text to be completed
    ;; starts with a `-'.

If partial completion happened before rather than after a leading `-'
maybe that would fix the problem?
