how did you get the merge tracking information if (as you mention
below) you don't use svn_client_log4() yet? Or do I misunderstand
something here?

What happens if merge info is not available for a revision? Does the
cache re-fetch it from the repository?

That's not a problem.

I think to update authors/comments, the users can use the 'clear log
cache' in the settings dialog. A refresh in the log dialog should not
invalidate the cache IMHO.
