OTOH, the user already supplied two revisions (-rN:M). I guess your
suggestion is more correct ... but to me peg vs. operational revs have
always felt overly complicated and unintuitive. Can't it, like, imply a
peg revision of N, instead of HEAD? So to get the (more complex) case
of HEAD's path node at where it was in revs N and M, I'd have to say
-rN:M path_at_HEAD. That would break with the other svn client UI, right?

Hmm, what does svnrdump actually do upon reaching a copy-here? Does it
continue dumping revisions of a different path? Does the normal peg-rev
thang even apply to svnrdump like it does to 'svn log'?

On the same thought, I'd love to be able to do
  $ svn rm ^/path
  Committed revision 7
  $ svn log ^/path
and be told that ^/path was removed in revision seven, instead of that
^/path does not exist. I *know* that it exists, *somewhere* in
history! Just, svn makes it awfully hard to find out where.

I've been wondering for a while: what *is* the best way to find out in
which revisions a given fixed path has existed and in which not? Few
years ago I wrote myself a little svn python API test that does just
that, I called it lograil (staying railed on the same path, no matter
what). I think that 'svn log' should have an option that does that.
Like 'svn log --fixed-path', and it tells you the revision ranges
where the path existed and where it was modified. Or does svn already
have that functionality?
