[PATCH v2 5/5] merge-ort: miscellaneous touch-ups

["Elijah Newren via GitGitGadget" <gitgitgadget@gmail.com>]

From: Elijah Newren <newren@gmail.com>

Add some notes in the code about invariants with match_mask when adding
pairs.  Also add a comment that seems to have been left out in my work
of pushing these changes upstream.
