what is ``not true'' is false and what is ``not false'' is true.
Using this test, the @code{if} expression works as follows: when the
! value of the variable @code{buffer} is actually a buffer rather then
its name, the true-or-false-test returns false and the @code{if}
expression does not evaluate the then-part. This is fine, since we do
not need to do anything to the variable @code{buffer} if it really is

This expression does not directly determine whether the killed text in
this command is located before or after the kill text of the last
! command; what is does is determine whether the value of the variable
@code{end} is less than the value of the variable @code{beg}. If it
is, it means that the user is most likely heading towards the
beginning of the buffer. Also, the result of evaluating the predicate
