You could download with Wget as usual and then make a flattened
copy of the tree Wget created with something along these lines
(not tested) :

  find tree -type f -print0 | perl -0ne 'chomp; $pathname = $_;
    $newpathname = $pathname; $newpathname =~ s{[&/address@hidden;
    symlink "$pathname", "$newpathname" or die "$newpathname: $!";'

The catch, of course, is that any links whose target contains
slashes will be broken. To fix that you would have to either
do the name translation from inside Wget (so -k knows about it)
or find a third party program to fix the links for you

Not sure how well symlink() works on Windows -- you might have to
do a straight copy instead.

Not familiar with cmd and tcsh but sh shouldn't have too many
problems with "%" (as long as it's not the argument of a job
control built-in), "&" (as long as it's quoted or escaped) or
"=" (as long as it's preceded by a command name). What is it
that you cannot get to work with sh ?
