svn blame not working for files which had binary mime-type in a previous revision

Hi,

I would like to bring up an old issue here:
http://subversion.tigris.org/issues/show_bug.cgi?id=2089
I've just bumped into this, and first it was really confusing why would svn
blame work with one xml file, but not with the other, as the
Skipping binary file: 'reference/apc/book.xml'
wasn't really helpful.
I understand that the discussion back in 2004 didn't reached an agreement
about how to resolve the issue, but could we at least change the error
message to something like:
Skipping binary file: 'reference/apc/book.xml' as binary mime-type was
found in revision X, use --force to proceed.

This would at least lessen the confusion on the users part.

ps: please cc me to the replies as I'm not subscribed to the list.
