[patch] extra verbose

[Alexander Nyberg]

I've always wanted some kind of indicator of time remaining on copying
files. This patch adds a 20 '.' long counter to show progress on files
larger than 500kb with -v flag (maybe should be -vv?).

I couldn't really follow the indentation though, I think it needs some
clean up.
