Re: [PATCH v7 21/31] merge-recursive: add a new hashmap for storing file collisions

Directory renames with the ability to merge directories opens up the
possibility of add/add/add/.../add conflicts, if each of the N
directories being merged into one target directory all had a file with
the same name.  We need a way to check for and report on such
collisions; this hashmap will be used for this purpose.

The same comment on compiling applies here.
Nice to review, but it may not compile due to unused functions
that a strict compiler may not be happy about.
