To you.  I find it less readable than the above.

For those of us who started with ed/vi, certain paradigms
evolved - such as ensuring the function name for a function
definition starts in column 1 so you can easily find it
using /^function-name, so

  int 
  main(...)
  {
  }

is preferrred over

  int main(...) {
  }


Likewise, the opening brace for the function should start
a line (supporting the '[[' and ']]' vim commands).

(and '%' use useful to match braces).

Indentation should be a sufficient visual cue without wasting
whitespace on useless blank lines.

    f = fdopen(fd, "r");
    if (f == NULL) {
        lp->log("Unexpected error re-opening '%s': %s\n",
                filename, strerror(errno));
        close(fd);
        goto done;
    }
