surround.vim vimpulse extension

Did anybody else use surround.vim? I've missed it ever since I switched to Emacs. Finally, last night, I got up the energy to hack something together: http://gist.github.com/487846 Things that work: * Changes surrounding enclosures * add surrounding enclosures * delete sounding enclosures Not working yet: * Surround region with a tag * non-visual surrounding of regions (IE: ysiw") * repeat surround modifications I'm not extremely happy with my approach on how I'm looking into the delete/change commands. Basically, I'm hijacking them in doing an advise (as in defadvice) approach. Feedback welcome, but mostly, I hope this is enjoyed by somebody else. Tim
