That's what I more or less expected as well. The full changelog is a good 
starting point to create the release notes though. So I will limit my 
scripting to output the log entries in a readily reusable format. The person 
creating the news page can then further reduce the output as he sees fit.

Ok for me.

I copied the bug title directly from bugzilla and didn't pay attention to the 
# sign, sorry.

I wanted to correct this with:
$ svn propedit --revprop -r18488 "svn:log"
But I am not allowed to do so:
svn: Revprop change blocked by pre-revprop-change hook (exit code 1) with 
Sorry [gjanssens], you cannot change [svn:log]
