"TypeError: Cannot read property 'start' of null" because of inline JS return statement

[strugee]

I have the following Jade template (reduced down to a testcase):

- if (object) return;

When compiling this with either jade template.jade or jade --client template.jade, I get:

/usr/local/Cellar/nvm/0.31.1/versions/node/v0.12.14/lib/node_modules/jade/node_modules/with/index.js:115
    return src.slice(node.start, node.end).join('')
                         ^

I don't want to use Pug since it's still an alpha, so I'm on Jade 1.11.0, running on Node 0.12.14 installed via nvm.

- condtion = false
- result = (condtion === "hohoho" ? "Its hohoho" : "Its not hohoho")

if result
  p.
    #{result}

@strugee, yep, that looks like a legitimate bug in the with module we are using. I have a patch ready, but I'd like to first bring that module under the governance of @pugjs so we can better maintain that: pugjs/with#11. See also pugjs/with#12 for a patch fixing this issue.
