master c7e297e: Prevent ElDoc blinking when eldoc-documentation-enthusiast is used

[João Távora]

branch: master
commit c7e297e90669dfa7f77eb4eb2b5c846f90fa0b23
Author: João Távora <joaotavora@gmail.com>
Commit: João Távora <joaotavora@gmail.com>

    Prevent ElDoc blinking when eldoc-documentation-enthusiast is used
    
    This eldoc-documentation-strategy function didn't always obey protocol
    since it returned nil sometimes, which the eldoc engine took it as a
    hint for the "old" protocol to clear the echo area.
    
    * lisp/emacs-lisp/eldoc.el (eldoc-documentation-enthusiast):
    Return t.
    (Version): Bump to 1.9.0
