I agree, the delete option should only appear when viewing the HEAD
revision.

You cannot delete *any* historical data. That is the purpose of a
revision control system to preserve data. The only way to do it is
described in the subversion book, and requires that you dump the
repository, use svndumpfilter, then reload it.

I think you are right. It is not possible, at least on windows, to check
out a complete revision which contains files differing only in case. Of
course you can do "Save as..." from the repo browser.
