The tree serves the layout: /layout, /tag and /col/<n>/tag

A script could not see where the panes sit or edit the tags a person
clicks in. /layout lists each column, its index, x and width in cells,
current or not, empty or full, and its panes' serials, then the active
column; /tag is the workspace tag and /col/<n>/tag a column's, read and
written as a pane tag is (one line: a newline written in is a space, and a
truncating write drops the one ending it); /index's lines end with the
pane's column; the log says newcol <n> and delcol <n>. acme serves no
column files, and the docs say so.
