Ignore white space at the start of argument / links

[baryluk]

I often copy links from browser or webpage, and use X=xclip -o; echo Downloading "$X"; youtube-dl -l "$X", or something like that. This make it possible, that if I copy a space before or after a URL, it will be not matched against regular expression, or when passed to be downloaded as webpage. This should fix it:

diff --git a/youtube-dl b/youtube-dl
index 5224611..b466c15 100755
--- a/youtube-dl
+++ b/youtube-dl

        all_urls = batchurls + args

Thanks.
