The problem is that you have a parser (I mean what vim does when skipping) there and it is not correct and may not be correct with this rule in effect. This statement in the help file exists since the first version recorded in mercurial repository and was also found in a 6.0 version archive: ":exe 'if'" was never correct. I just ask to make it not only officially incorrect, but also not working. Though it worked in 6.0 as well (not when skipping, of course). > > -- > BODY: I'm not dead! > CART DRIVER: 'Ere.
