;; HACK Eglot removed `eglot-help-at-point' in joaotavora/eglot@a044dec for a
;; more problematic approach of deferred to eldoc. Here, I've restored it.
;; Doom's lookup handlers try to open documentation in a separate window
;; (so they can be copied or kept open), but doing so with an eldoc buffer
;; is difficult because a) its contents are generated asynchronously,
;; making them tough to scrape, and b) their contents change frequently
;; (every time you move your cursor).
