Strange indent here.

It is interesting why you use "forwardslash", "space" and "wildcard" variables? Concat operator has no problems with string literals on either side of itself. And do not use '!= "cancel pressed"'.

Also why are you preceding some commands with a colon? I use it in two places: in *noremap definitions because it is required to enter command mode and after :autocmd/:command: as an element of coding style used to separate (auto)command body from the rest of arguments (preceding colon(s) are simply ignored so you may safely use them for various things like I do).
