Well it's good that this thread has produced more examples where it's
reasonable and acceptable to exceed 80 characters.

What do people feel about files where the policy is to place all the
parameters passed into a function on the same line, regardless of its
consequent length?  

(What kicked this all off was a patch Mikulas submitted containing many
long lines, one of which hits column 264.  Personally, I dislike reading
code with lines that wrap, but using a 132-column terminal width is
fine.)
