Return types that consist of more than one word need to be enclosed in
braces, see Info node `(texinfo) Typed Functions'. Otherwise they are
indexed incorrectly.
* doc/lispref/internals.texi (Module Misc, Module Nonlocal): Enclose
multi-word return types in braces.
* doc/emacs/search.texi (Special Isearch): Clarify slightly
(bug#19924). (All the keys in this node is about what happens
during isearch, but that information is quite a ways away at this
point, so it doesn't hurt to repeat that info.)
