The face code goes to some lengths to handle inheritance, so that all
the face properties from text properties and all overlays are combined
into the final displayed result.  The way keymaps are handled is a
little simpler: the highest-priority overlay with a keymap property (or,
failing that an underlying keymap text property) is used for the local
map.

In the past, it's been pretty painful making sure face inheritance works
just right.  So I can't say I'm enthusiastic about implementing anything
similar for local keymaps...
