Date: Fri, 14 Aug 2009 02:28:21 +0300

> `delete-pair' is deleting what it documents -- instead of removing the
> open paren of the following sexp, it deletes the current one.  So, if
> the cursor is on some whitespace that precedes an expression, the
> whitespace is deleted, and the open paren is left intact.

This should be fixed with the following patch:
