[Bug-wget] Downloading from us.ua hoster

[ptrk mj]

Greeting everyone,

I would like to download a file linked from http://us.ua/792900/ page.
The url rests inside <form> element:

<form action="http://u4-4.us.ua/download/"; method="post" id="fDownload">
   <input type="hidden" name="server" value="">
   <input type="hidden" name="file" value="792900">
   <input type="submit" id="sdButton" value="Скачать">
</form>

To retrieve it I could use:
wget --post-data=file=792900 http://u4-4.us.ua/download/

and it works but is troublesome because it requires a manual search
inside page source for a <form> element and it's contents. Isn't it
possible to call wget like this:

wget {options}... http://us.ua/792900/

and make it do the search for me?
