+* Fix memory leak related to aliasrun(). Precmd, Cwdcmd etc. leak memory.
+
+* Fix migrate -site $$... Seems to hang... (aix370)
+
+* Fix history in loops.
+
+* New idea.
+	Lots of people seem to like the idea to be able to do sed type
+	operations on shell variables. Maybe we can extend the syntax
+	of the variable editing to understand string operations.
+	So I would like to be able to use:
+	> set a="this is a STRING"
+	> echo $a:[3-]
+	is is a STRING
+	> echo $a:[#]
+	16
+	> echo $a:[6-7]
+	is
+	> echo $a:[-2]
+	ng
+	> echo $a:[-20]
+	Subscript out of bounds.
+	> echo $a:[2-20]
+	Subscript out of bounds.
+	> echo $a:[1-1]:u$a:[2-].
+	This is a string.
+
+* Fix pipelines that contain builtins so that they behave correctly.
+  I tried to fix that (most of the code is in sh.sem.c, but it works
+  only for non POSIX machines cause otherwise the setpgid() I added
+  fails).
+
+* Fix the correct code... How to do that involves A.I....
+
+* Rewrite the whole thing. It has taken to much beating over the years...
+
+* Add another hook like precmd to be executed after the prompt but before the
+  command.
+
+* Add instructions for using configure in the README file.
