Later we use lookup-key in this way:
(lookup-key aux-map (kbd (car cmd)))
which was slightly different from how we were defining the keymap which resulted
in M-j & M-k not being bound or displayed properly.
Fix test failure in when testing original section bindings:
+ `((,(copy-keymap magit-file-section-map) "\C-j" magit-diff-visit-worktree-file)
+ (,(copy-keymap magit-hunk-section-map) "\C-j" magit-diff-visit-worktree-file))
Move setup files into subdirectories. Move mode directories to modes subdir.
This will make it easy to specify a recipe in melpa that maintains the directory
structure. Add interactive functions to jump to .el and README files
