doc : remove \ from wget command
doc : remove \ from wget command

The wget command is broken in the documentation.  By using a \
to continue the command on another line, unfortunately line does not
render a newline character after it.  As such, a copy and paste
fails miserably.  Removing the \ allows a copy and paste operation.
