I strongly recommend using the continue statement here:

      while(putchar(' ') && --count) continue;

The reason is that the semicolon by itself is almost unnoticeable and you can create a difficult to understand malfunction if you don't notice you forgot to type it.

Another habit I have is to avoid a statement like:

    if (abc == 42)

and write it as

    if (42 == abc)

instead. The compiler will issue an error message if you type only one = in the latter form, whereas the first form will happily execute by setting abc to 42 and always taking the true clause.
