filectx: shortcut unrelated files in ancestor() (
issue1327)
merge: first part of fix for
issue1327
When there are no renames involved, we shortcut to the changeset
ancestor. This resolves most cases.
Note that Mercurial's rename philosophy elsewhere is that a file's
name is signficant and rename data is only consulted when a file of
the same name is absent.
