* lisp/org-exp.el (org-export-remove-or-extract-drawers): Changed funcall to run-hook-with-args-until-success to properly run the org-export-format-drawer-function hook. The problem was that funcall was being executed on the hook (list of functions) instead of running the hook with run-hook-with-args-until-success, which tries to run potentially a list of hooks until one returns non-nil. ~>Bill
