Multiple Lines Title

My blog titles are quite long. I’d like them to be displayed in three lines on the Index page.

My titles are almost all calibrated the same, for example:

Article 001 – Doctrine and Discipline of Divorce, John Milton

I’d like to see such a title displayed as follow :

Article 001
Doctrine and Discipline of Divorce
John Milton

That is, removing the ” – ” and the “, ” (with the spaces before and after) and replacing them (for the display only) by a carriage return.

How can I change the PHP of my index.php and single.php files so that my long titles will be replaced by three-lines titles? Naturally, if a title doesn’t contain ” – ” and “, ” I’d like it to remain unchanged.
