`file.info(string)/file::info.new(string)`是否解析符号链接?

File.info(string).symlink? 当它在以下示例中应返回true时返回false:

`mkdir -p /tmp/delete`
 Dir.cd "/tmp/delete"
`rm -f b`
`touch a`
`ln -s a b`

puts File.info("b").symlink?.inspect  # false
puts File.info("b").type              # File
puts Process.run("test", "-L b".split).success? # true
puts Process.run("test", "-L a".split).success? # false
