Show me the usability study with claims that 80 columns is the wisdom in software engineering. Why not 73, 90 or 95? The only reason for the 80 columns is a historic one. And the programming rules for linux doesn't manifest the 80 character per line. Code will get in many cases harder to read, especially together with the tab size of 8. Multiline C statements makes the code IMHO harder to read.
