-BROKEN: the "M b" line should not be there
+The "M b" line in the hg status output used to not exist, but the changes in
+b63351f6a246 caused the ordering of operations to change such that the dirstate
+gets written out at a different time. This causes the 'hg status' in the middle
+to think that "b" is modified. Note that strictly speaking isn't wrong since c4
+does actually modify "b".
+
+Regardless, we're more interested in testing what happens to 'hg status'
+afterwards, both with and without fsmonitor.
