  At this point, a shameless plug feels appropriate.
  The execline language was precisely made for this kind of script:
it spares users the hassle of understanding shell quoting, it does
the right thing in every case ; and for such small scripts, launching
a shell brings non-negligible overhead, whereas launching an execline
script costs practically nothing.

#!/command/execlineb -S0
busybox wget -T xxx $@

does exactly what it looks like it should be doing, even if arguments
contain special characters, and without any unnecessary system call
overhead.
