I have done this a couple of times, but every time WordPress comes out with a new version, it overwrites my changes and I gotta do it again. I know some plugins provide an alternate locations for stylesheets, so you can customize them and not be overwritten when it's updated. Is there any way I can put a file in another folder that will always override the default wptexturize? (Actually I think it's called formatting.php, but you know what I mean. I hope.)
Like if I put it in my theme folder, would that work?
Or possibly disable it in functions.php and write some sort of re-direct code in functions to point to the new file?
