Re: Diffs between %s and %s end here (was: vc-set-mode-line-busy-indicator)

    When I produce a diff before committing a change, I often want to make
    sure the no unintended/other changes crept in.  I expect to see
    exactly the diffs, not some disturbing additional lines.

How do you check that they are exactly the same diffs?
Do you use M-x compare-windows?  When that comes to the end
of the diffs in both buffers, the fact that one has a note
saying "end of diffs" won't make it harder for you to tell
that the two are identical.

    I almost never want to save compilation output buffers (or include it
    in a mail message), but I often do for diffs.

I don't think that end-of-diffs message will do any harm when you save
or mail the diffs.  In an email there will usually be other text both
above and below the diffs, in any case.  Adding one line of more text
below the diffs won't change the situation much.

                                                   Additionally, in
    compilation mode, it is more clear that this line is not part of the
    output because the bold words are in green or red:

We could put colors into the notice in the diff buffer
just as we do in compilation mode.
