# It assumes a Unix shell, and runs both mergeall and diffall 
# over a large but private content collection; edit settings
# to test your content.  Logs have been trimmed for privacy,
# and rerun to discount a no-cache penalty for the first test.

# Results:
# - normalization messages okay: 
#     new in 3.3
# - diffall message diffs okay (below):
#     3.2 prints NFD (decomposed, on macos)
#     3.3 prints normalized NFC (composed, via normalization)
# - all else same, and runtimes unchanged
