os: Improve File.Seek documentation #6978
Description
Currently, the documentation on os.File.Seek mentions: Seek sets the offset for the next Read or Write on file to offset, interpreted according to whence: 0 means relative to the origin of the file, 1 means relative to the current offset, and 2 means relative to the end. It leads people to write things like file.Seek(0, 2) which is in my opinion, not that readable, especially when you don't know where those numbers come from. I believe it would be better if the following os constants were mentioned instead: * SEEK_SET * SEEK_CUR * SEEK_END
