    Flymake: protect against problematic invalid diagnostics
    
    If a backend reports a diagnostic which is out of bounds, it still
    lives in flymake--state and will still be cleaned up in the next run
    of flymake--publish-diagnostics.  But if flymake--highlight-line
    doesn't give it an overlay (which it didn't until now), things will
    break afterwards.
    
    See bug#66759 and https://github.com/joaotavora/eglot/discussions/1311
    
    * lisp/progmodes/flymake.el (flymake--highlight-line): Set
    flymake--diag-overlay earlier.
    (Version): Bump to 1.3.7.
