polipo reopenLog() bug?

Dear Juliusz,

Thank you very much for a very useful piece of software, polipo!

I think there is a small bug in the implementation:

void
reopenLog()
{
-    if(logFile) {
+   if(logFile && logFile->length > 0) {
        FILE *f;
        f = fopen(logFile->string, "a");


Thanks,
Yury
