Since the --extrude option is typically only used for testing perltidy,
this type of error should not normally occur in practice.
+ In some rare instances the formatting can oscillate between two states
+ The following example was sent by Denis Moskowitz, Oct 29 2010:
+
+ grep { $_->foo ne 'bar' } # asdfa asdf asdf asdf asdf asdf asdf asdf
+ asdf asdf asdf @baz;
+
+ With standard parameters this oscillates between the above and:
+
+ grep { $_->foo ne 'bar' } # asdfa asdf asdf asdf asdf asdf asdf asdf
+ asdf asdf asdf @baz;
+
+ A workaround here would be to make a slight change to the side comment
+ length.
