Having reformatted *a lot* of code to libstdc++ style recently, the 80-column 
limit had me scratching my head and investing time better spent elsewhere 
(IMHO) way too much.

I'd object to staying at 80, FWIW. ;-) Going to 100 cols is an improvement. 
And I agree with others in this thread, it shouldn't be a hard limit. If the 
semicolon lands on column 101 does an additional linebreak really help 
readability?

There's another topic that came up in this thread: how to best indent after a 
line break. After indenting way too much code manually, I wrote https://
github.com/mattkretz/vim-gnuindent. You can see how it indents in its 
test.cpp. Maybe this is useful for some of you. :-)

Cheers,
  Matthias
