Yeah. My favorite example is JS-2 mode[1]. It's a brilliant mode for editing JavaScript released by Steve Yegge. However, it had some shortcomings and (minor) bugs; Yegge did not have time to support it any more. [1]: http://code.google.com/p/js2-mode/ http://code.google.com/p/js2-mode/ Then somebody cloned it on GitHub[2], changed the indentation, fixed some bugs and added some features. In the past, using JS-2 mode was a bit of a compromise--intelligence at the cost of weird behavior. Now there is no compromise at all.
