Publishing the source is what asks for it: a modified version has to carry prominent notices saying it was modified, with a date. These files already added a Coffey Labs copyright line beside upstream's, which implies as much without saying it; now they say it. 38 files, found by diffing against the merge base with upstream rather than by guessing. Upstream's own notices are untouched. The build is unchanged.
