When Wget fetches a URL to store into a file with a URL-derived name,
it can easily open the output file after it knows that the download has
begun.
With "-O", multiple URLs are possible, and so Wget opens the file
before any download is attempted. Consider:
wget -O fred http://www.gnu.org/ http://www.gnu.org/nonexistent
Here, one fetch works, and the other does not. Is that successful or
not?
Wget could probably be changed to delay opening the "-O" file until a
download succeeds, or it could detect any output to a "-O" file, and do
a delete-on-close if nothing is ever written to it, but it'd probably be
simpler for the fellow who specifies "-O" to do the check himself.
