You know, that function bar is declared in file baz.el. So you could
inspect the revisions of baz.el by looking into directory
"/home/albinus/src/emacs/lisp/baz.el@@/master" (given you're interested
in branch master).

Could be, yes. Likely, it needs some adaption of dired-jump (it uses
file-name-directory for traversing the directory path), but why not.
