db option not recognized in 1.38

[hedges333]

Trying to do cover -db /tmp/cover_db with v1.38.

Unknown option: db
Invalid command line options at /[omitted]/lib/perl5/x86_64-linux/Devel/Cover/Report/Html_minimal.pm line 714.

I tried adding it as HARNESS_PERL_SWITCHES=-MDevel::Cover=-db,/tmp/cover_db and that didn't help either.

Thanks.

In bin/cover I found it's undocumented that I can run it as cover /tmp/cover and it will shift the DB path from @ARGV.
