I just wanted to chime in - I have been so grateful to roath's suggestion to use this hardware to extend the straps since it has made my bag even more perfect! I purchased the same clips as she did and they've worked out great for me. I've been using my bag for over a month without any urge to switch out to another - I think a record for me. 
The clips alone make a significant difference in the length, but I also purchased these keychain split rings (B2020 7/8" Antique Brass, Key Ring, Solid Iron) to extend it just a smidge more.
