jQuery 1.10.x had a source map comment (the second line of the minified script), so Developer Tools features (like Google Chrome Developer Tools, perhaps Firebug, perhaps Internet Explorer F12 Developer Tools, perhaps Firefox Developer Tools) load the uncompressed script and let you debug jQuery using it. It will not be loaded by the browser if the Developer Tools feature is not activated by the user.
In other words, do not worry about it, it will not load for the regular user.
You can disable loading it by going to the Google Chrome Developer Tools feature, clicking on the cog wheel button and unticking "Enable JavaScript source maps". Then even when the Developer Tools feature is activated (well, yours, specifically), it will not load the source map or the uncompressed script.
