v0.6.1 (merge commit f850ef6) moves qc/ to a278ee8: QC-WF-001 criterion 2
records the workflow-directory check. The only difference from v0.6.0 is that
pointer and the changelog. CHANGELOG.md says v0.6.1 for the unreleased pin
change instead of v0.6.0.
Tests 305 passed; changelog check passes; the wiki build writes 0 pages.
