I agree. Also it is common for a loop to have multiple exits, and I don’t 
like treating one of them as a special “termination condition” above the 
others, so I like to use “break” for all of them.

The “for” form not only caters for this, it allows handy initialization of 
local variables that keep their value between loop iterations. E.g.

    for (unsigned int i = length_of(array);;)
      {
        if (i == 0)
          {
            ... not found ...
            break;
          } /*if*/
        --i;
        if (... array[i] matches what I want ...)
          {
            .. found ...
            break;
          } /*if*/
      } /*for*/
