One can already control o->detect_rename via the -Xno-renames and
-Xfind-renames options.  I think the documentation should mention that
"false" is the same as passing -Xno-renames, and "true" is the same as
passing -Xfind-renames.  However, find-renames does take similarity
threshold as a parameter, so there's a question whether this option
should provide some way to do the same.  I'm not sure the answer to
that; it may be that we'd want a separate config option for that, and
we can wait to add it until someone actually wants it.

I would expect an explicitly passed -Xno-renames or -Xfind-renames to
override the config setting.  Could you check if that's the case?

Also, if someone sets merge.renameLimit (to anything) and sets
merge.renames to false, then they've got a contradictory setup.  Does
it make sense to check and warn about that anywhere?
