Only 2 years passed, and I finally read the new code.

I have to say it's a solid improvement over the previous related change.

And one peculiarity: if I'm not mistaken, the value of next-error-buffer 
itself is never used in the current code, there's only the check 
(local-variable-p 'next-error-buffer) that references it, effectively 
turning it into a buffer-local boolean.

But it could probably still be used in custom values of 
next-error-find-buffer-function.

Too bad it didn't solve the flymake+next-error-function problem, but 
that seems more difficult.

Some rough idea: pick some similar keybinding in flymake-supported 
buffers ('C-c C-c'? wouldn't it be too presumptuous to take over?)... 
and make it, I don't know, echo the error text? Or (!) show the 
diagnostics buffer, for which there's no default key binding still. And 
in the end, call next-error-found.
