Dear developers of wget,

If you find some free time, would you, please, implement a feature that would progressively download a file that is growing on the remote site?

Though it might be obvious, let me explain what I mean.

In real world, some files might grow on the remote filesystem, eg. files that are being dumped, streams, ongoing download of larger file, etc. If we want to get these, currently, we need to run something like this several times consecutively:

wget -c http://www.mydomain.com/file.asf

...until the file has stopped growing (eg. certian tv stream was dumped).

The "--ignore-length" is not taken into consideration, (logically) when using "--continue" as it needs to count the difference in size between the downloaded file and the remote file. However, the file is downloaded only up to the content-length it retrieved on the last invocation of "wget -c".

Thanks and all the best in 2012!
