Hello,

I'd like to avoid annoying "No such file or directory" error raised by
auth-source-pass-entries to share my init.el on machines which may have
no ~/.password-store setup.

- OK: Empty ~/.password-store/

  mkdir ~/.password-store
  ./src/emacs -Q

  (require 'auth-source-pass)
  (add-to-list 'auth-sources 'password-store)
  (auth-source-search :host "host.example.com" :user "user")
  => nil

- Error-1: No ~/.password-store/

  rmdir ~/.password-store
  ./src/emacs -Q

  (require 'auth-source-pass)
  (add-to-list 'auth-sources 'password-store)
  (auth-source-search :host "host.example.com" :user "user")
  => (file-missing "Opening directory" "No such file or directory" "/Users/naofumi/.password-store")

- Error-2: ~/.password-store is not a directory

  touch ~/.password-store
  ./src/emacs -Q

  (require 'auth-source-pass)
  (add-to-list 'auth-sources 'password-store)
  (auth-source-search :host "host.example.com" :user "user")
  => (file-missing "Opening directory" "No such file or directory" "/Users/naofumi/.password-store")

A small patch is attached.

Best regards,
  Naofumi
