A middle or right sweep over a column's or the workspace's tag runs or looks for what it swept, as a pane tag's does

Both headers acted on the press: a middle or right press ran, or looked
for, the word under it (or the header's selection when it was on that) at
once, so a drag had nothing left to do. A sweep of `echo SWEPT` in a column
tag ran a bare `echo`. They have done so since the headers were drawn apart
from the panes; it is no regression, and the -l/Restore allocator fix
(ompukopz) does not touch it.

Now a press on a header holds a HeaderSweep (the column by its serial, or
the workspace), which the drag extends, held to the header's row and text
as a pane tag's sweep is. It is painted in its button's tint meanwhile, and
the release runs what it swept in that header's context; a release that has
not moved runs the word or selection a click always did. The other of
middle and right cancels it (acme 2-3/3-2); the select button is inert, as
a header's command already takes the held selection as its argument.

Running on the release, a builtin from a header is announced as one from a
pane tag is: the press used to set the announcement and the release clear it
at once. find, restore, theme, topbarexec, ttyhelp, tutor and windowops
re-recorded for that badge alone.

headersweep.snap sweeps the column and workspace tags with the middle
button and a word part with the right one, and cancels a sweep;
headersweep-restored.snap sweeps both after Dump and Restore.
