Hi,

This seems like an obvious "one-word" bug ("save-excursion" should be
"save-restriction"), so I'll be brief, but please let me know if more
details would be helpful.

Steps to reproduce: when using flymake with
flymake-show-diagnostics-at-end-of-line set to t in a narrowed buffer,
the narrowing goes away after a couple updates.

I traced this down to the function noted in the subject.  Changing
save-restriction to save-excursion fixed the bug for me.

Thanks, best,

Paul
