Check LogTooManyItemsThreshold per parent

A merge commit shows the differences for both parents. When there have been many changes in the target branch the threshold can be reached although the merged branch may only change a few files. So the LogTooManyItemsThreshold is now considered per parent. This way you see the few changes of the merged branch and discard only the changes from the target branch.

Thank you for working on this MR!

I like this change in principle, however, the change looks kinda large. That's why I'm hesitating to merge ATM.
