I am so sorry that the review of this takes so much time :-( - but I
suppose most of the people have the same problem - not understanding
enough scripts to be able to test reliably.
I tried to push your patch so that it functions only in the Experimental
mode (that you can switch it on in the Options... dialog); unfortunately
the patch modifies too low-level stuff be able to make use of that
Anybody here with ideas what we can do so that the patch helps Khaled,
and is as safe as possible? - so that we can commit it, and fix the
consequences later if anything happens?
Thank you a lot,
