suggestion to download to folder with auto file name

[Brano]

Hi dear,

I'm using wget for years now. Thank you for that. I suggest you to 
modify the "-O" parameter to not only file, but also directory.

"-Ooutput.html" work as saving to file "output.html" - its OK

"-Ooutput" work as saving to file "output" - its OK

"-Ooutput" should work as saving to "output" directory if directory 
exist with automatic file name acording to html name from file I'm 
downloading.

Thank you again
