Import Contacts Step 2 - Field Names Font not Red

In 4.2 the field names 'Email', 'External Identifier', First Name', 'Internal Contact ID' and 'Last Name' were display used a red font on the 'Import Contacts step 2' webpage when importing individual contacts. The field names are listed in the "Matching CiviCRM Field' drop-down selector. Also there is an Asterisk at the end of the name.

In 4.3 the names are not displayed using a red font nor do they have an asterisk.

I didn't looked at importing Households or Organizations. They might also have field names that should be display red also.
