The annotated example of a complete working Flymake backend leaves process buffers around

[Rudolf Adamkovič]

I noticed that the "annotated example of a complete working Flymake backend" at

<https://www.gnu.org/software/emacs/manual/html_mono/flymake.html#Backend-functions>

leaves zombie buffers around. I traced the problem down to

┌────
│ (when (eq 'exit (process-status proc)) …
└────

The backend kills the process buffer on `'exit' but not on `'signal', which 
happens when Flymake kills an obsolete in-progress check. I fixed the problem 
locally with

┌────
│ (let ((status (process-status proc)))
│   (when (or (eq status 'exit) (eq status 'signal))
│     …
└────

I think we should fix the Flymake manual as well.
