[texhax] natbib: same authors and year citations

[jtzzaa11-texhax at yahoo.com]

Hello,

I've figured out the natbib issue. The problems seems to be arise only when there multiple references in the same cite command. Specifically:

\citet{Smith:2000:a} ... \citet{Smith:2000:b} will correctly produce two different references, for example Smith (2000a) and Smith (2000b).

\citet{Smith:2000:a, Jones:2010} ... \citet{Smith:2000:b} also works as above.

However, \citet{Jones:2010,Smith:2000:a} ... \citet{Smith:2000:b} erroneously produces two identical references, namely, Smith (2000), for both Smith:2000:a and Smith:2000:b.

Joel.
