I wanted to explain why I wasn't using /dev/null, especially since
that's what the Perl version used and that phrasing is preserved in
the current comment:

  # magic hash for Git (git hash-object -t blob /dev/null)                        
  _EMPTYBLOB = 'e69de29bb2d1d6434b8b29ae775ad8c2e48c5391'

So how should I more clearly explain why I prefer stdin to /dev/null?
Maybe “… is more portable than the /dev/null path (which doesn't exist
on Windows, for example).”?

Cheers,
Trevor
