Fix problem in `g' in Info with strings like "(foo)"

* lisp/info.el (Info-find-file): Add a new parameter to avoid
jumping to the directory if the user looks for a filename on the
form "(foo)" that doesn't exist.
(Info-read-node-name-1): Use it to allow completing over strings
like "(foo)" without losing focus (bug#30091).
