(isearch-within-brackets): New variable.
(isearch-mode): Set that.
(isearch-edit-string): Bind that.
(isearch-search-and-update): Set that.
(isearch-top-state): Set that.
(isearch-push-state): Use that.
(isearch-search): Set that.
cross-reference but located somewhere on current line, make
cross-reference the `default'. If only one cross-reference
located in node, make it `default'.
neutral values. Save the outer values in debugger-last-command, etc.
Put those saved values back into effect when returning.
(debugger-eval-expression): Put the saved values into effect
while evaluating, and store modified values back into
debugger-outer-... after evaluating.
(enable-flow-control-memstr=): Function deleted.
(enable-flow-control-on): Use member instead.
(flow-control-c-q-replacement, flow-control-c-s-replacement): New vars.
absolute file names culled from error msgs.
(compile-abbreviate-directory): Prepend comint-file-name-prefix (if boundp)
to DIR before other processing.
(shell-prefixed-directory-name): New defsubst.
(shell-process-popd, shell-process-pushd, shell-process-cd,
shell-resync-dirs): Apply it to ARG when it's a directory name.
Use (concat comint-file-name-prefix "~") in place of (getenv "HOME") or "~".
Call cd instead of shell-cd.
(compilation-forget-errors): Reset compilation-parsing-end to 1 here.
(compile-reinitialize-errors): Don't reset compilation-parsing-end after
calling compilation-forget-errors.
Comment out gratuitous switch-to-buffer call; what was the rationale for it?
Don't check compilation-parsing-end (removed local AT-START); instead
always append to compilation-old-error-list, it will be nil if at start.
If compilation-error-list is non-nil before calling the parser, restore its
previous value afterwards; it still indicates the current error position.
Subtract the length of the existing compilation-error-list from
FIND-AT-LEAST when calling the parser.
(compilation-parse-errors): Don't check LIMIT-SEARCH at end of loop.
Inside check it inside each case of the cond; in error case we must discard
the last new error before stopping (just as for FIND-AT-LEAST).
Use floating-point in buffer percentage calculation, to avoid integer
overflow.
