Condition: run Emacs in terminal, or otherwise without fringes.

Unconditional resizing happens here:

             (flymake-mode
              ;; The buffer about to be annotated is visible.  Check
              ;; necessary conditions to auto-set margins here (bug#77313)
              (let* ((w (and (eq flymake-indicator-type 'auto)
                             flymake-autoresize-margins
                             (visible-buffer-window))))
                (unless (flymake--suitably-fringed-p w) 
(flymake--resize-margins)))


When flymake-autoresize-margins is nil, W just gets bound to nil, which 
makes flymake--suitably-fringed-p evaluate the current window. And if it 
doesn't have fringes, flymake--resize-margins is called.

It's probably not a problem most of the time, but can be puzzling when 
one is debugging margin resizing behavior. It might create conflict with 
some other hypothetical package as well.

This 'let*' could be turned into 'when-let*'.
