[João Távora]

branch: scratch/flymake-refactor-cleaner-for-emacs-26
commit 4f7d5681226213cd74031af01c6716fc9af70d77
Author: João Távora <address@hidden>
Commit: João Távora <address@hidden>

    Flymake checks file names before considering diagnostics
    
    The error patterns for gcc picked up errors for the Makefile itself,
    for example.  These shouldn't count as actual errors.
    
    * lisp/progmodes/flymake.el (flymake-report): Check
    matching file names.
