[Rd] 2nd sentence of ?attributes has a typo (PR#7060)

[Weigand.Stephen at mayo.edu]

The second sentence of the Description of ?attributes has 
a typo. Either "the" or "an" (but not both) should be deleted. 

  Description:
  
       These functions access an object's attribute list. The 
       first form above returns the an object's attribute list.

(I'm using 1.9.0 now, but the typo also exists in 1.9.1 
for Mac OS X.) 

Thank you,

Stephen
