The field's presence is to allow us to improve over CVS, to make log
messages reliably parsable. It would be a step backwards to reintroduce that
I agree that including separators in log messages is rare, but there's at
least one rather valid use-case: including all relevant logs for the
revisions of a merge in the merge commit.
Disallowing separators in messages seems like an unpleasantly inelegant
thing to do, and creates an awkward corner case when it comes to svn 1.x ->
2.x migration. Also, I'd hate to have to explain the reasoning to someone
using a GUI client.
Regarding the user confusion issue - I think the proper way to fix that is
to explain the lines field in the svnbook.
