Thanks for the advice, Jim. I was going for an all-or-nothing approach
(leave
all conflicts in, or try to eradicate all of them), but it does seem like
some of
them are quite easy to resolve, and others don't matter at all if they
happen
rarely. I'll take care to see if there are any other solutions, and that
it's
important, before going to the application-level conflict resolution.
