[ruby-core:18325] Re: [Bug #449] File.zero? returns true when given a directory on Windows

I submitted that original bug (first time using redmine :)). Here's some mo=
re context:

File.zero? on Windows when given a directory name produces a nonsensical re=
sult. It should do one of the following:

1) Provide consistent results given a directory name on both Windows and *n=
ix
2) Throw an exception since File !=3D Directory

Since 2) is not the Ruby Way, it makes more sense to either do 1), or mark =
its behavior as "undefined", or "platform specific" which will let individu=
al implementations decide how to define it.

Does this sound reasonable to folks?


Thanks,
-John
