[Bug-wget] Running wget with -O and -q in the background yields a file wget-log

[Tomas Korbar]

Hello,
when quiet option is provided and wget runs in background an empty log file
is created. I think this file is obsolete because quiet option prevents any
log to be written into that file. This problem is caused by redirection of
logs. Wget checks only if it is running in background and then redirects
logs to default log file and initialization of logs creates the file which
stays empty.This problem can be fixed with simple patch which i am
attaching.
