If you wrote
+ target_cmd_root($ho, <<END, $timeo);
+ $useproxy wget --progress=dot:mega -O \Q$path\E \Q$url\E
and $url contained
http://chars $"'\ considered harmful.iso
then target_cmd_root would get
http_proxy=something wget --progress=dot:mega -O \/some\/path \
http\:\/\/chars\ \$\"\'\\\ considered\ harmful\.iso
And:
mariner:~> echo http\:\/\/chars\ \$\"\'\\\ considered\ harmful\.iso
http://chars $"'\ considered harmful.iso
mariner:~>
But maybe this is too ugly, in which case you could use ''
and some regexp like s/['\\]/'\\$&'/g (not tested).
