Would somebody pull this already? 3 months! I need this.

Please note #40 which looks similar.

Also looks similar to #140, #61.

Meanwhile, you can use custom delimiters like so in your .vimrc:

let g:NERDCustomDelimiters = {
  \ 'racket': { 'left': ';', 'leftAlt': '#| ', 'rightAlt': ' |#' },
\ }

That being said, is there anything particular we can do to get this PR merged, @scrooloose ?

Fork notice: With the upstream project sitting stale after nearly 8 months since the last activity, 71 outstanding pull requests, no comments from the original developer, and dozens of developers duplicating efforts while scratching their own itches, I've decided to step in and run a fork for a while. Hopefully the original developer will eventually consider picking this plugin up again or adding more maintainers so that the user base doesn't end up fragmented, but for now I would invite anyone interested in the latest updates to consider installing from and contributing pull requests to my fork.

About this PR: I have updated this patch to resolve the merge conflict and merged it to my fork. Please consider installing the plugin from alerque/nerdcommenter for this and (so far) over two dozen other updates.

Change of plans. I've been added as a maintainer here so this will be merged to Github shortly. Actually it already has been but Github is having issues at the moment and the CDN isn't showing it yet but I expect it will shortly.
