So, you have a tmp_entry, you clear it and then assign to the only field
that will be used by the following call. How can that be necessary?

BTW, you can leave this svn_wc_merge_prop_diffs function alone for now.
I've left a TODO at the top (after you created this patch). We should look
into reimplementing this in terms of svn_wc__install_props.

Hmmm, maybe I missed that, but it needs to do this before going in.
Compatibility, you know... :-)

Nah, maybe not now when I rethink it. I was thinking about a function that
this isn't. If you document in the public struct that propcaching is wc
format dependent, then everything is clear IMO.

Also, please see my TODO item for using existence of has_props attribute
for optimizing svn_wc__has_props, which is actually necessary by the
status code.

Thanks,
