[elpa] externals/elpa 4e82f53 53/71: Reload Eldoc if needed on Emacs < 28

[João Távora]

branch: externals/elpa
commit 4e82f53f17a5df0737c353a5ce811a6f6cc9a366
Author: João Távora <joaotavora@gmail.com>

    Reload Eldoc if needed on Emacs < 28
    
    ElDoc is preloaded in Emacs, so `require`-ing won't guarantee we are
    using the latest version from GNU Elpa when we load eglot.el.  Use an
    heuristic to see if we need to `load` it in Emacs < 28.
    
    * eglot.el (Package-Requires): Require eldoc 1.5.0
    (top): Sometimes load eldoc
