an output pane is not a document: +Search/+Help split below the pane that asked, never into a column of their own

placeDoc classified any file pane as a doc, so a +Search opened from a lone
shell took layoutInsertColumn(0) - a whole new leftmost column, shoving every
existing column sideways - and an open results list was then eligible as the
split parent for a real file, stacking documents under the list. An output
buffer has no file behind it and no Save; it is the result list belonging to
the pane that asked for it. Now it is that on both sides of the rule: it
splits below from_id whatever kind of pane that is (a source that died falls
back to stackDocLeft, the same last resort a full column bar uses), and it is
skipped when a real doc hunts for its split parent, so a file opened from a
search row joins the docs instead of the results.

Real docs are untouched: fsearch/rsearch/look-file/tutor/lookpanes all pass
unchanged. psearch is the proof - its results snap was two columns (the shell
pushed to x=70, its gutter run at 70-71) and is now one 140-wide column with
the +Search stacked below at the same x origin.
