Re: possible improvement to svn log with "forward" revision range

I wanted to take a closer look into implementing this feature and have built the current SVN trunk.
I have looked through the code and now i have a rough understanding how the log information is collected.

As far as i know the history is always collected from youngest to oldest revision (not the other way around).
Your suggestion to modify Y to the latest revision where PATH_at_PEG still exists looks like the easiest approach.
But i could not yet figure out how to perform this operation.

Could you give me an advice how this could be realized or point me to some other code area where a similar "forward" traversal/search is performed?
May be with some hints i can carry on with this by myself.
