[Emacs-diffs] emacs-26 4f38bde: Examine tex-chktex--process in the correct buffer

[João Távora]

branch: emacs-26
commit 4f38bdec743787bb4f00b51696afd3acf5a2e113
Author: João Távora <address@hidden>
Commit: João Távora <address@hidden>

    Examine tex-chktex--process in the correct buffer
    
    As in other Flymake backends, the process sentinel might run in
    arbitrary buffers where this variable's value doesn't make sense.
    
    For a way to trigger a problem due to this, see discussion starting in
    https://lists.gnu.org/archive/html/emacs-devel/2017-10/msg00645.html
    
    * lisp/textmodes/tex-mode.el (tex-chktex): Use
    with-current-buffer.
