RFC 6087 mentions "pyang --ietf"  and 
draft-ietf-netmod-yang-tree-diagrams mentions "pyang -f tree 
--tree-line-length 50"

If not in RFC6087bis, where would we document this?
As a rhetorical question: How many of the YANG doctors were aware of and 
are enforcing this command?

Background Info.
Typical question I've been receiving lately (in this case from IANA):
When requesting the final files from the RFC-Editor, the file they 
extracted using their tool and the yang modules appear to have a lot of 
blank space in them. Is this OK?
