+Eight arg KEEP-ALL, if non-nil, says to put all inputs in the history list,
+ even empty or duplicate inputs.
+If the variable `minibuffer-allow-text-properties' is non-nil,
+ then the string which is returned includes whatever text properties
+ were present in the minibuffer. Otherwise the value has no text properties.
+
+The remainder of this documentation string describes the
+INITIAL-CONTENTS argument in more detail. It is only relevant when
+studying existing code, or when HIST is a cons. If non-nil,
+INITIAL-CONTENTS is a string to be inserted into the minibuffer before
+reading input. Normally, point is put at the end of that string.
+However, if INITIAL-CONTENTS is \(STRING . POSITION), the initial
+input is STRING, but point is placed at _one-indexed_ position
+POSITION in the minibuffer. Any integer value less than or equal to
+one puts point at the beginning of the string. *Note* that this
+behavior differs from the way such arguments are used in `completing-read'
+and some related functions, which use zero-indexing for POSITION. */)

+ALIST can also be a function to do the completion itself.
+It receives three arguments: the values STRING, PREDICATE and t.
+Whatever it returns becomes the value of `all-completions'.
+
+If optional third argument PREDICATE is non-nil,
+it is used to test each possible match.
+The match is a candidate only if PREDICATE returns non-nil.
+The argument given to PREDICATE is the alist element
+or the symbol from the obarray. If ALIST is a hash-table,
+predicate is called with two arguments: the key and the value.
+Additionally to this predicate, `completion-regexp-list'
+is used to further constrain the set of candidates.
