but even using "$@" whitespace in a URL must be correctly
escaped or it will not work with busybox wget and with real wget.
The reason for this is the point when arguments get expanded or
split into words.
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.
