 If \fIparameter\fP is an array name indexed by @ or *,
 the result is the \fIlength\fP
 members of the array beginning with ${\fIparameter\fP[\fIoffset\fP]}.
+A negative \fIoffset\fP is taken relative to one greater than the maximum
+index of the specified array.
+Note that a negative offset must be separated from the colon by at least
+one space to avoid being confused with the :- expansion.
 Substring indexing is zero-based unless the positional parameters 
 are used, in which case the indexing starts at 1.
