Thanks for the patch you submitted. We are currently working on the
SVN 1.6 tree conflicts feature in the tree-conflicts branch, but we'll
review and start committing them soon.

It sounds like you are asking for the cache to just build this
information. All I can say right now, is that I cannot see doing
that. I do not even think it'd make sense to make it a preference.
There are just too many cases where it winds up running "forever". To
get back to your specific question, other than when you are refreshing
a specific file, the cache is always built on the repository root. So
if you want a rough idea of the cache, try running:

svn log -g -rHEAD:0 url://server/repos

I am sure there are lots and lots of repositories where that will run
reasonably fast. But on other repos, it almost never ends. For
example, on SVN's own repository, without the -g option the command
takes a few minutes. With it, it will run until you kill it. So
until there is a better way to get this information, I cannot see
changing it.

We added some cache maintenance in the repo browser, maybe you could
add an option there to "refresh" select folders and provide UI to
specify whether or not to get the mergeinfo? You'd still have a
problem that when the cache automatically adds new revisions, it will
do without the mergeinfo.
