Tab N sets a tab's width in cells, 1 through 16, in every pane, drawn and counted (wrapping, clicks, the cursor); bare Tab says it; the ctl read and a Dump keep it

A session setting, not acme's per window: the width is read by File's pure
width functions (~130 callers that are given no pane), so it is one value,
config.tab_now, that Runtime.apply sets and a new session resets. A file:L:C
column counts runes, as compilers do, and never depended on it.
