Subject: Properly handle the differences in hints in the optree with/without
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=be2b1c742382f74864880924170180bbe1904463;hp=ce5d06123ae0253bf2e33033ffbfba16ce3bb79e;p=p5sagit%2Fp5-mst-13.2.git

Properly handle the differences in hints in the optree with/without
use open; by adding the with-open hints to all the golden results,
and providing a new flag strip_open_hint to checkOptree().
