It's pretty good!  (Just try to remember to separate out the ChangeLog
entries from the rest of the patch - changelog patches are like a
walking time bomb they sneek in to the ChangeLog file where you least
want it :-)

It might take a little time to integrate though - people need to dust
off their old notes and go backthrough and cross off the random readline
tweeks that were needed.  Hi Elena!

How did the testsuite go?
