Comment link after successful download with --batch-file

• I've verified and I assure that I'm running youtube-dl 2018.06.25

• At least skimmed through the README, most notably the FAQ and BUGS sections

• Searched the bugtracker for similar issues including closed ones

• Checked that provided video/audio/playlist URLs (if any) are alive and playable in a browser

What is the purpose of your issue?

• Feature request (request for a new functionality)

Hi!

I read the doc, especially the Options part, and I'd like to make a request for a new option which I think shouldn't be a default behavior.

The new option would be to automatically add a comment character # ; ] to a batch download link after a (un?)successful download. In the case some links can't download and you absolutely want the whole list (using until ... do), youtube-dl wouldn't have to iterate over the whole batch file again and again.

Some pseudocode will make it more understandable hopefully :

for link in batchFile
    ...
    downloadVideo(link)
    ...
    if options.comment_link_after_successful_batch_download and link.isDownloadedSuccessfully
        newLink = '#' + link
        replaceInFile(batchFile, link, newLink)
    endif
endfor
