Fix obscure signal-handling bugs. These patches have been in my local shell build for almost 2 years. They were submitted to the es list about that time. We might as well add them to our port collection of fixes since I expect no further releases. Also, I noticed that bash in ports enables readline support by default. As it is painful to use es without readline support, I will do the same here. Fix: New file files/patch-ac
State Changed From-To: open->closed committed, thanks
