I'm completely unfamiliar with this code...

(defun completion-table-with-quoting (table unquote requote)
...
           (boundary (car (completion-boundaries ustring table pred "")))
           (completions
            (completion--twq-all
             string ustring completions boundary unquote requote))

ustring here is "~man", and the boundary is 1, so completion--twq-all
returns "/foo/~man" (because it stripped off 1 character at the start).

But it should have stripped off "~/foo/~", I think?  Somehow?
