I think there is a subtle difference. 2883 is saying if there was no
activity at all in the merge source, then we should not update the
mergeinfo on the merge target. I realize this is only a subtle
difference, and it could be argued that we ought to update the
mergeinfo. In this case, it seems like a reasonable optimization to
not do this which should be a little more friendly for scripters.
In your example, there were some changes merged, they just did not
explicitly effect the areas where the mergeinfo was updated. We
have been fairly clear that we want this to update the mergeinfo.
In fact there is third scenario, that Dan mentions on one of these
issues. The merge does not actually merge anything, but it does
"skip" some stuff. In other words, items were changed in the merge
source that do not exist in the merge target. In this scenario, Dan
was pretty adamant that we should still update the mergeinfo and I
agree.
Basically, we decided to treat the one scenario described in 2883 as a
"special case" based on feedback from several of the early adopters
that tried the code.
