Put the match (which you need in the replacement) in parenthesis (a  
capture), this will allow you to refer to it as $1-$n (for the  
numbered capture), e.g.:

    ${1/(.+?)\s*(\/\s*|$)/$1 does:\n$1 does not:\n/g}

This matches one or more characters (non-greedy), then optional  
whitespace followed by a slash (and more optional whitespace) or end- 
of-line.

So each match should be for an item in the list, including the / (and  
trailing whitespace), putting the actual item in capture 1, which is  
then used in the replacement.

You cannot -- it is however high on my own wishlist :)
