Running M-x checkdoc over the foo.el below I hoped it would ask to
capitalize "emacs" to "Emacs" in each of the three places.  A real-life
example can be found in `vi-save-all-and-exit' of vi.el.

I suspect the \\_> in checkdoc-proper-noun-regexp doesn't match a "." at
the end of a sentence.  Would relaxing that a bit like below cause any
false positives?

Incidentally, checkdoc-proper-noun-regexp could build its value with
regexp-opt could it?  Not that it needs to be optimized, just easier
than an explicit concatenating loop.
