mode with second element of compilation-arguments instead of third
to reflect latest changes in compilation-arguments structure.

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.

New defcustoms.
(next-error-no-select): Let-bind next-error-highlight to the value
of next-error-highlight-no-select before calling `next-error'.
"if current buffer is a next-error capable buffer" after the
rule "if next-error-last-buffer is set to a live buffer".
Simplify to test all rules in one `or'.

automatic rectangle padding feature; replace by non-destructive
virtual rectangle edges feature.
(cua-virtual-rectangle-edges): New defcustom.
(cua-auto-tabify-rectangles): New defcustom.
(cua-paste): If paste into a marked rectangle, insert rectangle at
current column, even if virtual; also paste exactly as many lines
as has been marked (ignore additional lines or add empty lines),
but paste whole source if only one line is marked.
(cua--update-indications): No longer use overwrite-cursor to
indicate rectangle padding
(cua--rectangle-virtual-edges): New defun.
(cua--rectangle-get-corners): Remove optional PAD arg.
