[Bf-committers] line length / code style.

[Campbell Barton]

This is not high priority of course but once in a while I notice
blender has some annoyingly long lines in our own source dir, eg.

Eventually it could be good to have a document like this for blender:
https://sites.google.com/site/openimageio/coding-style-guide

... until then, I'd like to set some reasonable line limit - Suggest
120 (80 would be is impracticable for us).

longer lines can stay where it makes sense - URL's for example.
