As there may be approval for some planned improvements to the SQL Formatter feature in 3.2, I logged an enhancement request for you: Bug 13744858 - FORUM: UNWANTED LINE BREAK AFTER CREATE OR REPLACE SYNTAX

But if you have control over your auto-deployment process code, it might be quicker to enhance that to deal with CREATE OR REPLACE on the same or the preceding line. Also, note that if you edit the package DDL to put the CREATE OR REPLACE on the same line with the package name in the code editor, then immediately use Export or Save Package Spec and Body to save it to disk, then PACKAGE <name> will appear on the same line as the CREATE OR REPLACE syntax.
