Paths: describe the anchor added on a selected segment as an end of its halves

Browse Source 
A selected segment that path.insertAnchor splits stays selected as its
two halves. The new anchor is the end both halves share, so it moves
with them, and Delete cuts both halves. docs/mcp.md and the comment on
renumber_after_insert called it a direct-selected anchor; they now
describe it as an end of the halves that moves with them.

`path.reshape {id, x, y, dx, dy, tol?, focal?, radius?}` (a Reshape tool drag) grabs the path at `x`, `y`, adding an
anchor there unless one lies within `tol` (3 by default), and moves that point by `dx`, `dy`.
