[Michael Albinus]

branch: master
commit 23a7da9148c84dbcc228dda37c9bcebfc2a004d2
Author: Michael Albinus <michael.albinus@gmx.de>
Commit: Michael Albinus <michael.albinus@gmx.de>

    Modernize use of prompts in auth-source.el
    
    * lisp/auth-source.el (auth-source-search): Adapt docstring
    (auth-source-format-prompt): Remove trailing ": ".
    (auth-source-netrc-create, auth-source-secrets-create)
    (auth-source-plstore-create): Adapt prompts.  Use `format-prompt'.
    Do not ask interactively if `auth-source-save-behavior' is nil.
