321 If optional second arg INITIAL-CONTENTS is non-nil, it is a string

322 to be inserted into the minibuffer before reading input.
|
|
|
323 If INITIAL-CONTENTS is (STRING . POSITION), the initial input
|
|
|
324 is STRING, but point is placed POSITION characters into the string.
|
|
|
325 Third arg KEYMAP is a keymap to use whilst reading;
|
|

326 if omitted or nil, the default is `minibuffer-local-map'.

331 and optionally the initial position in the list.

333 or it can be a cons cell (HISTVAR . HISTPOS).

334 In that case, HISTVAR is the history list variable to use,

335 and HISTPOS is the initial position (the position in the list
|

336 which INITIAL-CONTENTS corresponds to).
|

337 If HISTORY is `t', no history will be recorded.
|
|
|
338 Positions are counted starting from 1 at the beginning of the list.
