It seems like there might be some contention between where the encoding actually happens. I am passing true to qualifyPath so it doesn't escape:

As I am expecting it to be escaped in the runCommand function:

Code looks good to me. Replacing sanitize with noEscape is great...makes a lot more sense!
See my remark about that line being removed though.

@sebjulliand Not sure why I did that. Re-requested your review.

Approved and good to go!
