In all the other cases, --diff-merges=<short> is equivalent to
-<short>. Here, --diff-merges=1 and -1 do _very_ different things.
Is there any concern that might cause confusion? (My gut reaction is
this is probably fine and people won't try to make such a connection,
but it made me worry just enough that I thought I'd flag it for you
and other reviewers to at least mull over and maybe comment on.)
