ftpget potential security problems

ftpget.c consistently writes data into a 128 character array using
sscanf. Unfortunately, it doesn't do any bounds checking, allowing a
malicious FTP server to cause a buffer overrun. <sigh> When will we ever
learn...

I'll try to submit some patches, but I may not have time before I leave for
Europe, so if somebody else wants to take a crack at it, please do so.
