Great; I've applied your fix (along with the test) to Emacs 28.

Looks good to me.  The only detail is that we normally want the first
line of a doc string to be a complete sentence, and in one case it
wasn't:

+(ert-deftest cperl-mode-test-bug-10483 ()
+  "Verifies that a piece of code which ends in a paren without a
+statement terminato ron tne same line does not loop forever.  The

But this is in the test harness, so I don't think we really have much of
a style convention going here, so I didn't fix that up before applying.

Yeah...  Perhaps Emacs should grow some convenience functions for this
stuff?
