Thanks for the feedback gentleman.

I was unaware Artistic Style is dead. Haven't found a line length  
thing in it anyway. I am using Artistic Style for formatting because  
the default QtCreator coding style and a project level .astylerc of  

# If you have astyle installed on your Linux development machine and
# you have enabled it via Beautifier plug-in then this file will control
# how the beautifier formats the code.


along with a keyboard shortcut of <ALT><Shift><F> gets me the bulk of  
the way there. I have to manually view the ruler and fix which is fine  
since I'm merging multiple "test" projects into something usable, but,  
the "official" requirement states "an automated tool." Might see if we  
can get overrides for that.
