[Stefan Monnier]

branch: master
commit b8f9e58ef72402e69a1f0960816184d52e5d2d29
Author: Stefan Monnier <monnier@iro.umontreal.ca>
Commit: Stefan Monnier <monnier@iro.umontreal.ca>

    * lisp/minibuffer.el (completion-in-region--single-word): Simplify
    
    Remove redundant args `collection` and `predicate` which were always
    equal to `minibuffer-completion-table` and
    `minibuffer-completion-predicate` anyway.
    
    (minibuffer-complete-word):
    * lisp/emacs-lisp/crm.el (crm-complete-word): Simplify accordingly.
