Is there any way to remove the "- Site Name" from the page title?

Instead of this:

<title>This is a Post - Site Name</title>

I would rather it be:

<title>This is a Post</title>

This is because the favicon already identifies the site, making the title more clear and less redundant. It has also been becoming a thing on popular social networks.

I know this may seem like a superficial change, but I couldn't make it with templates.

Is there any way to do this? - I have the same issue. My Site Name contains words that are often used in Thread Names and the Page Titles are very long.
