Error parsing stylus output

[jylauril]

Running StylusLint as a pre-commit hook and it looks like the object that is being stdout'd gets cut so the JSON is no longer parseable.

Example output:

Analyze with stylus linter................................[StylusLint] FAILED
Warnings:

I fixed some of the warnings and reproduced this every time when the stdout exceeds 8194 bytes. From googling I found this issue: nodejs/node#12921 where their limit seems to be 8192 bytes (which is too close to be a coincidence) and the issue seems to be exactly the same. Not sure if that will help with the investigation, but godspeed.

Expected: bacon
Got: ham
