I've been playing with the e command and, yes, it is a tad bit different, but appears close enough. I'd be fine with it (I don't know what other customers using the VIM CUA would think).
I do have a question, though, how do you delete the last <whitespace> delimited word?
I can delete the last natural word, but that only deletes the word back to the first encountered /. If I tab to fast, I lose what I first started typing and find I have to delete the entire command bar and try again (e.g., e fo<tab> may go to e some/really/long/path/to/formulate.c when I needed to get at some/other/path/foo.c) I'd rather a single keystroke that would delete the entire path and let me reenter (sort of like a ^W in vim mode with any of the : commands).
I didn't see anything obvious looking at the online help (other than multiple keystrokes to essentially perform the single keystroke I'm used to)
