27 ;; documented in the Emacs user's manual.

37 "Non-nil means `query-replace' should do character folding in matches.
38 This means, for instance, that ' will match a large variety of
39 unicode quotes."
45 "Non-nil means `query-replace' matches a sequence of whitespace chars.
46 When you enter a space or spaces in the strings to be replaced,
47 it will match any sequence matched by the regexp `search-whitespace-regexp'."
53 "Non-nil means `query-replace-regexp' matches a sequence of whitespace chars.
54 When you enter a space or spaces in the regexps to be replaced,
55 it will match any sequence matched by the regexp `search-whitespace-regexp'."

100 The value of this variable should be a symbol; that symbol
101 is used as a variable to hold a history list for replacement
102 strings or patterns."
