make -column lists pretty again;

specifically, rewrite them to permit some markup in the column headers,
and use "Ta" instead of literal tabs; mandoc does not currently match groff
100%, but a mandoc fix may be some time off, and we've gone enough releases
with poorly formatting column lists.

in some cases i have rewritten the lists as -tag, where -column made
little sense.
