context: clarify the various mode in the _copies property cache

The previous code was compact but a bit dense. The new proposed code deal with
each mode separately, there are some duplicated lines, but the meaning of each
mode stand out.

One of the benefit it to make it simpler to add further mode in the future.

TODO: Can merge non-conflicting changes outside narrow spec

  abort: merge affects file 'outside/f1' outside narrow, which is not yet supported (flat !)
  abort: merge affects file 'outside/' outside narrow, which is not yet supported (tree !)
  (merging in the other direction may work)

Refuses merge of conflicting outside changes
