determining what was updated, using client hook scripts

*tl;dr* - I wish the POST-UPDATE client hook received (as an argument) a
file containing the explicit list of paths/files updated.

Hello, I'd like to outline a problem I've worked through in the hope that
A) there is an easier way or B) that I might hear feed back if this is
worth asking for an enhancement over.

For my build environment's needs I need a list of which files were updated
when a client has updated the working copy. I currently achieve this by
the following inefficient technique.

First) During PRE-UPDATE I use a TortoiseSVN hook to capture the output
from:
svn --status --verbose --xml <PATH>
where PATH is derived from the PATH file handed to the PRE-UPDATE hook.
 So, basically I inventory the working copy , dumping the results into a
structure.

--then--

Second) During POST-UPDATE I again inventory via the svn verbose status
command , and now I have a before and after set and from these I subtract
and decipher exactly which files where updated.

This is slow. It works - but it is slow. What I would greatly like is to
have access (at the client script level) to the information being displayed
in the TortoiseSVN window itself. Right there on the screen are the very
file paths I'd be interested in - but no such feature seemingly exists.

Anyone ever explore this? Perhaps there is a much better way to decipher
what files exactly were updated during an update? Perhaps this is
something useful to suggest as an enhancement? I'm interested in your
responses, thanks in advance,

Alex
