316 If fourth arg READ is non-nil, then interpret the result as a lisp object
|
|
|
317 and return that object:
|
|
|
318 in other words, do `(car (read-from-string INPUT-STRING))'
|
|
|
319 Fifth arg HISTORY, if non-nil, specifies a history list
|
|
|
320 and optionally the initial position in the list.
|
|
|
321 It can be a symbol, which is the history list variable to use,
|
|
|
322 or it can be a cons cell (HISTVAR . HISTPOS).
|
|
|
323 In that case, HISTVAR is the history list variable to use,
|
|
|
324 and HISTPOS is the initial position (the position in the list
|
|
|
325 which INITIAL-CONTENTS corresponds to).
|
|
|
326 If HISTORY is `t', no history will be recorded.
|
|
|
327 Positions are counted starting from 1 at the beginning of the list.
|
|
|
328 Sixth arg ABBREV-TABLE, if non-nil, becomes the value of `local-abbrev-table'
|
|
|
329 in the minibuffer.
