This is for use in conjunction with another command such as svn blame.
That's where the "associated path" comes in in this point.
Eg:
svn blame somefile.c
(read, see revision number you care about)
svn log -rRevnum somefile.c |less

So don't do that. Subversion has tags so you can say: svn log
repo/my/tag, and see the related log message.
So, yes, if you intentionally use the command wrong, the results will
not make sense. :)
This is the entire point of my previous message: A revision number
without an associated path is meaningless. If you give a revision number
and some random path which is not really associated with, you will get
meaningless results. That's the point.

The whole point of this thread seems increasingly to be "I do not
understand how svn implements tags"
Paths always have revision numbers associated with them. ("node IDs", I
suppose). If you create a Tag in SVN, as currently implemented, all you
are doing is attaching a name to a collection of related nodes at a
particular revision. You can call the tag whatever you want.

If you are mis-using SVN to the point where paths become meaningless,
perhaps you should re-read the book ;)

It's a tag. Why would I care what revision it was comitted to? I just
want to know "Show me release 13", not "Show me a random number which
happened to come up when release 13 was made".
