Thank you. I understand this description and it make sense to me. I'm
unfamiliar with the merge code so have to rely on you who are the
experts for a sanity check.
I will remove the separate merge.aggressive config setting and instead,
set the aggressive flag when the renames is turned off (whether by the
new merge.renames setting or by the -Xno-renames flag) as Elijah suggests.
