[Emacs-diffs] master ff9ddda: Simplify pre-write-conversion for utf-8-hfs coding system

[David Reitter]

branch: master
commit ff9ddda9069da6b4dbcc64615cb4cab9a1f4f8b7
Author: David Reitter <address@hidden>
Commit: David Reitter <address@hidden>

    Simplify pre-write-conversion for utf-8-hfs coding system
    
    * lisp/international/ucs-normalize.el
    (ucs-normalize-hfs-nfd-pre-write-conversion): Refactor.
    
    May address an issue where Emacs consumed large amounts of CPU
    because of neverending toolbar updating (which was caused
    by, but also called this function).
