Well, it's not hard to write a script to determine the last changed
revision given a URL:

$ lastchangedrev.sh http://svn.collab.net/repos/svn/tags/1.4.2
22210

You can incorporate that into other shell commands directly; no need
to transcribe any revision number by hand:

$ svn log http://svn.collab.net/repos/svn \
-r`lastchangedrev.sh http://svn.collab.net/repos/svn/tags/1.4.2`
------------------------------------------------------------------------
r22210 | maxb | 2006-11-04 06:00:43 -0600 (Sat, 04 Nov 2006) | 1 line

Tagging release 1.4.2 with svn_version.h matching tarball.

You can write any manner of scripts to simplify what you see as
routine Subversion operations, if they are not already simple enough
for you to use day to day.
