[ELPA Syncer]

branch: elpa/paredit
commit 901acb8a614c9f309365d933889e7433bed1ee90
Author: Taylor R Campbell <campbell@mumble.net>
Commit: Taylor R Campbell <campbell@mumble.net>

    Changes for version 16.
    
    - Introduced M-S (paredit-split-sexp) to split lists or strings from
      the middle.
    
    - Fixed the definition of M-; to use (kbd "M-;") to correctly
      identify the key sequence meta-semicolon, not "M-;" for M hyphen
      semicolon.
