I eventually got around to revisiting the compile error regexps I made
for perl test scripts in my compilation-perl.el.

I was misguided about the "NOK" business of the perl--Test::Harness one
that's now in emacs.  I believe the three symbols perl--Test,
perl--Test2 and perl--Test::Harness can be replaced by the two simpler
bits of compile.el.perl.fragment below.  compilation.txt fragment below
too, to replace the two sections "* Perl Test module error messages" and
"* Perl Test::Harness output".

	* progmodes/compile.el (compilation-error-regexp-alist-alist):
	Replace/amend perl--Test, perl--Test2 and perl--Test::Harness with
	better patterns perl--Test and perl--Test-failed.
