mode with second element of compilation-arguments instead of third
to reflect latest changes in compilation-arguments structure.
(recompile): Use global variable `compilation-directory' to get
recent compilation directory only when `recompile' is invoked NOT
in the compilation buffer. Otherwise, use `default-directory' of
the compilation buffer.

(isearch-pop-fun-state): New defsubst.
(isearch-top-state): Call function saved in `isearch-pop-fun-state'.
(isearch-push-state): Set the result of calling
`isearch-push-state-function' to the `isearch-pop-fun-state' field.
(isearch-cancel): Call function saved in `isearch-pop-fun-state' to
restore the mode-specific starting point of terminated search.
(isearch-abort): Call `isearch-cancel' instead of its duplicated code.
(isearch-repeat): Call `isearch-wrap-function' if defined.
(isearch-message-prefix): Don't add prefix "over" to the message
for wrapped search if `isearch-wrap-function' is defined.

restore the mode-specific starting point of failed search.

(isearch-word, isearch-invalid-regexp, isearch-wrapped)
(isearch-barrier, isearch-within-brackets)
(isearch-case-fold-search): Add suffix `-state' to state-related
defsubsts to avoid name clashes with other function names.
(Info-search): Add new optional arguments for the sake of isearch.
Replace whitespace in Info-search-whitespace-regexp literally.
Add backward search. Don't call `Info-select-node' if regexp is
found in the same Info node. Don't add node to Info-history for
wrapped isearch.

Simplify to test all rules in one `or'.
(next-error): Doc fix.
