#113 Uploading new version fails with file is empty error

[Alex Efros]

I've just tried to upload new version of https://www.vim.org/scripts/script.php?script_id=3893 but got "viewdoc.zip is empty, are you sure you specified the correct path?" error. I'm 100% sure the file is not empty and it was correctly sent (I've checked content of browser's POST request).
