wput 0.4.1 bugreport + patch

Hello,
I tried your wput (0.4.1), but I get only segfaults. I found that
in utils.c in function parse_url() you change *url, when there is
"ftp://"; in it, and so the free(url) before return caused the
segfault.  I simply stored the original pointer in another
variable and it works fine now.

Another bug I found, when there is some long (more lines) server
reply (ie. log welcome.msg). Wput then reports an Invalid
FTP-Answer due to the

   if(p-msg < 4 || !ISDIGIT(msg[0]) || !ISDIGIT(msg[1]) ||
     !ISDIGIT(msg[2]))

condition when called recursively from 

   if(msg[3] == '-') get_msg(csock, msg, buflen);

I did some simple workaround which works for me, but I tested it
only on proftpd server which I use. I hope that this will help
you in your work, because I found wput very useful.

Regards,

Stepan
