[Alan Mackenzie]

branch: master
commit b7e59b9e194ac287fe627ccb26159d2f6f04939b
Author: Alan Mackenzie <acm@muc.de>
Commit: Alan Mackenzie <acm@muc.de>

    c-find-decl-spots: Replace an arbitrary search limit by a parameter
    
    The old arbitrary limit led to errors thrown whilst fontifying large areas 
of
    syntactic whitespace containing "#undef", as in src/comp.c.
    
    * lisp/progmodes/cc-engine.el (c-find-decl-spots): Replace the limit 
argument
    to two calls of c-forward-syntactic-ws by the parameter `cfd-limit'.
