On the contrary -- you're desiring something quite complex in
Subversion. Subversion's filesystem is optimized with respect to tags
and branches in *exactly* the opposite direction from CVS.

   - To make a tag or branch in CVS is an O(N) operation across all
     the files included in the tag. In Subversion, it's O(1).

   - To see a list of tags and branches that file belongs to in CVS is
     O(1). In Subversion, it's currently not possible (for a couple
     of reasons[1]), but would be something quite a bit > O(1) if it


[1] This operation isn't possible in Subversion for two main reasons:

    - we can currently crawl version history of files only in a
      backwards direction (youngest to oldest), and we need to be able
      to also crawl forward.

    - we don't discriminate between branches and copies (which, despite
      some of the opposing theory spouted on this list, really are
      different version control operations), so the answer you'd get
      about a list of such things could contain false positives.
