# This file exercises a problem in Wget, where if an error was

# From bug report. :)

I've included log output (using the -d switch) from when this happens
below. You'll see that for the retry wget sends a REST command to
reset the start position before starting the RETR command. I'm
confused about the argument to REST: 51132. It's the full length in
bytes of the file to be retrieved. The RETR then shows the entire
contents of the file being skipped, and wget announces that it
successfully retrieved and saved 0 bytes.
