Wrong - if you want to get the same attributes as the source, you need to
pass those attributes (how will put() guess them if you pass -1 to it ???).
This is KIO::put(), not copy(), it doesn't know the source file.

- -1 means "use default permissions, those coming from the umask".

Permissions != -1 are usually those of the source file (e.g. when put()
is called by FileCopyJob, called by CopyJob::copyNextFile).

The analogy with command-line tools isn't as easy as looking at "cp -a" BTW.
If you _edit_ an existing file (even as another user), it never changes its permissions.
Isn't resuming a download in this case too? IMHO it shouldn't chmod the target.
Maybe this is what the fix was about - not applying the permissions when resuming.
Which still means they should be honoured when completely _overwriting_
the destination file. This would also be consistent with the KDE_open code above.

Which leads to this patch instead:
