Is there a way to get a nice list of all commit messages sorted by file? Something like this (as you can see, I don't want the messages specific to a certain file, just show messages for the entire commit if the file was part of the commit, repeats ok):

-- index.php
    2010-01-02 03:04:05
      * added new paragraph
    2010-01-01 03:04:05
      * moved header out of index.php into header.php
      * header.php initial check-in
    2009-12-31 03:04:05
      * index.php initial check-in

-- header.php
    2010-01-03 03:04:05
      * added new meta tags
    2010-01-01 03:04:05
      * moved header out of index.php into header.php
      * header.php initial check-in

Additional information:

svn log filename does something similar, but I want it to do this:

1. get a list of files that have changed between yyyy-mm-dd (r2) and yyyy-mm-dd (r4) (i.e.

   svn log -q -v -r 2:4 > changedfiles.txt

2. strip extraneous crap from changedfiles.txt
3. svn log each file in that list, as in:

   svn log < changedfiles.txt >> combinedlog.txt

   (just pseudocode, i know svn log takes arguments not input, but can't be bothered to write it out)
