[Emacs-diffs] emacs-26 491cc4a 13/39: Flymake checks file names before considering diagnostics

[João Távora]

branch: emacs-26
commit 491cc4a1bd68c2f651027982e3dfb7545d3e57ab
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.
