[Emacs-diffs] master 4309d15: When looking for the end of a declarator, prevent macros fouling up the search

[Alan Mackenzie]

branch: master
commit 4309d1574ae86244751600171b605b2b2eca4697
Author: Alan Mackenzie <address@hidden>
Commit: Alan Mackenzie <address@hidden>

    When looking for the end of a declarator, prevent macros fouling up the 
search
    
    The practical implication of this bug was a random jit-lock chunk remaining
    entirely unfontified.
    
    * lisp/progmodes/cc-mode (c-fl-decl-end): If point starts inside a macro,
    restrict two forward searches to the end of that macro.
