No, I think this is a good bugfix patch that stands on its own, and
further cleanups could be done independently on top and should not
block this patch from being merged to master.

I'm inclined to think that this should be merged and then
'so/log-diff-merge' should be queued on top because of the subtle
interaction between this bug, the new config variable and the
completion tests.
