why "(void)printf(fmt);" besides lint(1)?

Personally, this is one of the few places where I just refuse to use the
cast.  I consider it pointless clutter.  If lint objects, tough.

In the (relatively rare) event that I seriously care whether printf output
got out intact (fprintf output I often care about, but not printf), I check
ferror(stdout) afterwards.  That also lets me do one check after a number
of printfs, and avoids portability hassles over the return values.
