### Maybe useful for calling (legacy) conflict resolvers that expect one
### property conflict per invocation.

MARKER_ABSPATH is the path to the file containing a human-readable
description of the conflict, MINE_PROPS and THEIR_OLD_PROPS and
THEIR_PROPS are all NULL, and CONFLICTED_PROP_NAMES is an empty hash.
