'Howdy,' replacement string replacement no longer working in WordPress 4.7, again in 4.8

[bobbingwide]

In WordPress 4.7 a change was made to the logic that translates the 'Howdy,' string.
From $howdy = sprintf( __('Howdy, %1$s'), $current_user->display_name );
To $howdy = sprintf( __( 'Howdy, %s' ), $current_user->display_name );

See https://core.trac.wordpress.org/ticket/37794

oik is still using the original string to re-run the translation, but it no longer gets translated due to the parameter format change, so oik's string replacement logic no longer works.

Proposed solution

• The code in oik needs to reflect the change to core.
• It's not necessary to make the code backward compatible with earlier versions of WordPress.

Now it doesn't work in 4.8 - see https://core.trac.wordpress.org/attachment/ticket/40342/40342.2.diff - part of WordPress TRAC 40342.
The current user display name is now within a span class="display-name" tag.
