Added ?w to all CSS files

Hi,
It's not a disaster, but all CSS file calls made with question mark and letter w:
<link type="text/css" rel="stylesheet" media="all" href="/modules/book/book.css?w" />
<link type="text/css" rel="stylesheet" media="all" href="/modules/node/node.css?w" />
<link type="text/css" rel="stylesheet" media="all" href="/modules/system/defaults.css?w" />
<link type="text/css" rel="stylesheet" media="all" href="/modules/system/system.css?w" />
<link type="text/css" rel="stylesheet" media="all" href="/modules/system/system-menus.css?w" />
<link type="text/css" rel="stylesheet" media="all" href="/modules/user/user.css?w" />CSS can't accept GET parameters, so what's the point of adding "?w" ? Is it a bug or a feature?
Thanks,
Jacob.

from the code :
// A dummy query-string is added to filenames, to gain control over// browser-caching. The string changes on every update or full cache
// flush, forcing browsers to load a new copy of the files, as the
// URL changed.
Thanks a lot,
