Documentation

Add NEWELT to the history list stored in the variable HISTORY-VAR.

Return the new history list. If MAXELT is non-nil, it specifies the maximum length of the history. Otherwise, the maximum history length is the value of the history-length property on symbol HISTORY-VAR, if set, or the value of the history-length variable. The possible values of maximum length have the same meaning as the values of history-length. Remove duplicates of NEWELT if history-delete-duplicates is non-nil. If optional fourth arg KEEP-ALL is non-nil, add NEWELT to history even if it is empty or duplicates the most recent entry in the history. HISTORY-VAR cannot refer to a lexical variable.
