Right-align headers over all-numeric columns with --right-align-numeric (#380) (#2167)

Browse source 
With --right-align-numeric, PPRINT data cells right-align but headers
stayed left-aligned, so a header did not line up with its own column's
data -- the original ask in #380. Now a header is right-aligned when
every value in its column is numeric, for both non-barred and barred
PPRINT output. Mixed columns keep left-aligned headers.

For --omd-aligned, the raw header text of right-aligned columns is now
right-justified too, matching how Markdown viewers render the ---:
marker; this follows the same all-values-numeric per-column rule
already used for the separator markers.

Man-page regeneration also picks up previously-merged reorder help-text
edits that had not been regenerated.

written in the order in which they are named with -g or -f, not in the
order in which they appear in the input records.
To deduplicate records by one or more fields while keeping all other

for each distinct value of the hash field, with all fields intact.
