Yeah, what Greg said.

Also very long identifier names like RefreshRateTableIndex
and simple dereferences like
	XGI330_RefIndex[RefreshRateTableIndex + (*i)].Ext_InfoFlag
make using 80 columns silly.

Just ignore 80 column limits when there are 20+ character
identifiers.  Ideally shorten the identifiers to something
less verbose and/or use temporaries where appropriate like
I showed in my reply to your suggested V5 patch.
