[BioC] problem with duplicateCorrelation and ExpressionSet objects

Dear Jenny,

I have double-checked by re-installing limma 2.10.4 from 
Bioconductor, and it seems that I failed to commit all the necessary 
files to the Release branch. My apologies. I have now committed limma 
2.10.5 which should be correct and complete.

I append a small reproducible example to show that the problem is 
fixed in limma 2.10.5.

Best wishes
