Black compatibility : relative vs absolute path

[Nodd]

I noticed a minor incompatibility between black and blackdoc: black displays absolute filenames in the console while blackdoc displays relative paths. This would not be a problem, except that is renders blackdoc incompatible with black-gl-code-quality. I think that it can be easily fixed on this side.

Here is the error:

$ blackdoc --check . 2>&1 | black-gl-cq
