    Flymake: use proper point-setting hygiene (bug#81621)
    
    A report touches the eol overlays whose style could be influenced by
    current-ish position.  Saving point and going back to it, isn't 100%
    accurate (point may have moved between scheduling and multiple reports),
    but it is probably more than decent.  A marker would be better but
    requires at least a buffer-local var for proper cleanup, which is
    overkill IMO.
    
    * lisp/progmodes/flymake.el (flymake-make-report-fn): Use
    point-marker and save-excursion.
