CHANGES file typo, or what (for svn 1.4.2)

Hi svn users:

In the CHANGES file, under User-visible changes, Client, it says:

"* fixed: 'svn status -u' fails in a read-only working copy (r21904, -19)"

Note the issue ID is "-19". Is this a typo?

I'd like to understand the scenarios that this fix affects.

Can someone point me at the issue, and/or explain? (is this Issue# 2583?)

We use Linux RHEL3 and RHEL4, svn version 1.3.2, and are considering an upgrade.

Does version 1.4.2 no longer use .svn/tmp for storing temp files
during translations on svn st, svn diff? IOW,
does this fis the problem where when a user does an svn st on a
working copy owned by some other user,
and they get permission denited on .xvn/tmp/foo Can't open foo?
when permissions oare 750 on .svn/tmp?

Or is this some other scenario that was fixed?

Thx,
Tim Noell
