Severity: minor

The commit 2020-09-04 "Fix infloop when indenting in cperl-mode" for
(Bug#10483) contained a test to make sure that indenting for some edge
cases.  This test 'cperl-mode-test-indent-exp' fails unless cperl-mode
is activated for the buffer.

The attached patch activates cperl-mode, and skips the test under
perl-mode, and avoids dependency on how inline comments are indented.

I couldn't just open a new bug without unarchiving the old one, perhaps
because I've included the old bug number.  Please tell me if it is
better to treat such follow-ups as entirely new bugs.
