[802.3_YANG] Maximum line length of YANG modules

[Robert Wilton <rwilton@xxxxxxxxx>]

Hi,

IETF YANG modules lines are restricted to 69 characters. This is because 
they are embedded into RFCS (max 72 characters/line), and the module 
ends up being indented by 3 spaces in the RFC.

For my updates to the 802.3 Ethernet YANG modules, I am also currently 
formatting the maximum line length to 69 characters, but I don't know if 
IEEE uses a higher limit for MIBs/YANG modules. If I should be using a 
different, higher limit, then please can you let me know, and I'll 
reformat the descriptions accordingly.

Thanks,
Rob
