Let me take a stab at what Alex means here...

Given the job of viewing a file's history, if I wanted to only view the last few log entries, instead of the available 10145 (which is HEAD), I could either use...

svn log filename | less

   or

svn log -r HEAD:HEAD-100

   The second of which is cleaner.

But what really intrigues me is HEAD+100 ... just imagine the possibilities of checking out HEAD+100!!! ;)
