Emacs: lin version 0.4.0

Lin is a stylistic enhancement for Emacs’ built-in hl-line-mode. It remaps the hl-line face (or equivalent) buffer-locally to a style that is optimal for major modes where line selection is the primary mode of interaction. In concrete terms: (i) let your theme use a subtle gray to highlight the current line in text-editing buffers like Org, and (ii) render the current line with a more prominent colour in Dired, Ibuffer, et cetera. Why? Because the two types of interaction have different requirements about how intensely the current line should be highlighted.

Sample configuration:

(require 'lin)

(setq lin-face 'lin-blue) ; check doc string for alternative styles

;; You can use this to live update the face:
;;
;; (customize-set-variable 'lin-face 'lin-green)

;; This is the default value
(setq lin-mode-hooks
      '(bongo-mode-hook
        dired-mode-hook
        elfeed-search-mode-hook
        git-rebase-mode-hook

The grep-mode-hook and proced-mode-hook are included in the default value of the user option lin-mode-hooks. This practically means that Lin will be active in the implied modes when lin-global-mode is enabled. Thanks to Nicolas De Jaeghere for the patch (Nicolas has assigned copyright to the Free Software Foundation).
The faces that leverage the macOS palette (lin-mac{,-override-fg}) are made to work with Mitsuharu Yamamoto’s emacs-mac port: https://bitbucket.org/mituharu/emacs-mac/src/master/. They read the mac display specification in addition to the ns one. Remember that you can specify the desired face as the value of lin-face (its doc string documents all the stylistic options we provide). Thanks to Kai von Fintel for the patch (the change is well below the ~15 line threshold for copyright assignment).
