[Emacs-diffs] emacs-26 a58d0c5 1/5: Fix loading of smie-config rules (Bug#24848)

[Noam Postavsky]

branch: emacs-26
commit a58d0c590a777be98e58cd8c92ee1381e07e9b2d
Author: Noam Postavsky <address@hidden>
Commit: Noam Postavsky <address@hidden>

    Fix loading of smie-config rules (Bug#24848)
    
    * lisp/emacs-lisp/smie.el (smie-config--setter): Use `set-default'
    instead of `setq-default'.
    (smie-config): Use `custom-initialize-set' instead of
    `custom-initialize-default' as the :initialize argument.
    
    * lisp/progmodes/sh-script.el (sh-learn-buffer-indent): Mention that
    we call `smie-config-guess' so that the user will have a chance to
    find the correct docstring to consult.  Remove hedging comments
    regarding use of abnormal hooks.
