Hmm, that's interesting.
Yes, it looks like an inconsistency on the surface, but I'm not sure
it's inconsistent when considered deeply...
When you receive a propset of svn:eol-style from the repository, you're
also receiving whatever effect that propset had on the file it was
committed on. That is, in the merge-from-repos case, the commit has
already taken place, so it's natural that the line endings would change,
along with the property, on the receiver's side.
IOW, receiving the propset via update/merge is not quite the same as
doing the propset manually in your working copy. One represents a
commit that actually *has* taken place, the other represents an intent
to commit.
So I think the current behavior should be preserved. I'm not saying it
was a conscious decision (it may have been, I just don't remember). But
I'm pretty sure we don't want to change a merge behavior that seems to
have been working well for some years.
Possibly we could change 'svn propset' to fix up the line endings at
propset time... But surely we must have considered that and decided
against? It's too obvious not to have been discussed. Did you see a
comment anywhere indicating why we don't?
