More improvements in the Emacs manual

* doc/emacs/maintaining.texi (Xref Commands, Identifier Search)
(List Identifiers): Insert blank lines between @item's in a
@table.
(Etags Regexps): More accurate description of escape sequences.
(Select Tags Table): Prefer "~/emacs.d/init.el" to "~/.emacs".
Suggested by Michael Albinus <michael.albinus@gmx.de> in
