* lisp/org-latex.el (org-export-latex-fixed-width): now checking
org-example rather than org-protected on verbatim export, because by
default all ": " prefixed lines are marked protected
thanks to Christopher Allan Webber for catching this
* lisp/babel/langs/ob-python.el (org-babel-python-table-or-string):
now more careful not to replace "None"s which are not isolated
portions of lists
Thanks to Christopher Witte for raising these issues
* lisp/babel/langs/ob-haskell.el (org-babel-expand-body:haskell):
replaced missing () wrapping, and now using correct variable
expansion
(org-babel-execute:haskell): now using
org-babel-haskell-initiate-session to start sessions
(org-babel-haskell-initiate-session): only starting sessions if none
exists, also added a .25 second wait on brand new sessions to allow
the Haskell interpreter to fire up
(org-babel-load-session:haskell): now optionally accepts processed
params to avoid over-execution of variable resolution
(org-babel-prep-session:haskell): now optionally accepts processed
params to avoid over-execution of variable resolution, also placing
the variable definitions directly in the session instead of loading
them from a separate file
* lisp/org-entities.el (org-entities): Restructure the list.
(org-entities-help): Turn the help output into a buffer
in Org-mode, so that it becomes easier to find a symbol

Thanks to Daniel Mahler for finding this problem and proposing the fix

Use `org-not-nil' to interpret a property value of nil.

The problem was here that the value of the property is the string
"nil", which is of course not nil.
This patches introduces a special case to interpret "nil" as nil.
