commit f0b9018f521292d970cdaed99c47e02b60026e52
Author: Brian Leung <bkleung89@gmail.com>
Commit: Stefan Kangas <stefankangas@gmail.com>

    Properly print error message of eglot-alternatives
    
    * eglot.el (eglot-alternatives): Work with the listified form. This
    allows presumed executables provided as (EXECUTABLE &rest ARGS...)
    to be displayed in the error.
