Subject: file-exists-p on empty string
Date: Wed, 27 Feb 2019 15:29:53 +0300	[thread overview]
Message-ID: <CAO=W_ZoyVv+WPfX2zeDjWXf16EJ=XpFbkQhqH8j5JSWZof80Dg@mail.gmail.com> (raw)

It was quite surprising for me that

  (file-exists-p "")
  ==> t

I thought that `file-exists-p` resembles stat, such as

  $ stat ""
  No such file or directory

This is because `file-exists-p` uses `expand-file-name`, which returns
current directory for empty string

Would not it be more correct for `file-exists-p` to return `nil` for empty
string, and if someone wants current directory he will use "." as filename?

Thanks
