[ELPA Syncer]

branch: elpa/page-break-lines
commit 4285943db3a51bab976c45a9f157878d62e070fa
Author: David Rothlisberger <david@rothlis.net>
Commit: David Rothlisberger <david@rothlis.net>

    Enable in derived modes of `page-break-lines-modes'
    
    For example if `page-break-lines-modes' contains `prog-mode',
    `global-page-break-lines-mode' will apply to `python-mode', `c-mode',
    etc.
    
    Tested on Emacs 24.2.
