Here is what I added on top of the 3-patch series for tonight's
pushout.

 * No need to count positive/negative; just seeing both exists is
   sufficient and there is no need to examine any later elements, if
   any.

 * Clearing commit marks needs to be done after we have seen enough,
   or it can clear the stuff we would want to inspect before we
   have a chance to.  Do it in a separate post-cleaning loop.

 * Dedent by judicious use of 'goto'.

 * The last parameter to setup_revisions() is a pointer, so spell it
   NULL not 0.

 * "rang" -> "range" typofix (it might be even better to look for
   "range:")
