format-patch serves one patch per commit, oldest first, and the diff views key the parsed files by name, so a file touched by several commits kept only the newest commit's hunks. a pull's "All changes" (and any range of more than one commit, on the pull, compare and compose pages) showed an incomplete diff: on tangled.org/core, spindle/repos.go across the last four master commits showed 16 changed lines instead of 27. those ranges now skip the patch and take their files from the combined diff; a single commit still streams its patch.
