[Emacs-diffs] master 3a47f39: Properly ignore stderr in elisp Flymake backend

[João Távora]

branch: master
commit 3a47f3921bdaaf7b7d80dc3be05a5f1b1f2501eb
Author: João Távora <address@hidden>
Commit: João Távora <address@hidden>

    Properly ignore stderr in elisp Flymake backend
    
    Naively passing `null-device' as stderr creates a buffer named
    "/dev/null" instead.  Pass a hidden buffer name instead.  (Bug#31902).
    
    * lisp/progmodes/elisp-mode.el (elisp-flymake-byte-compile): Pass
    hidden buffer as make-process :stderr instead of null-device.
