[BioC] [limma] 0 weights = removed from analysis?

[mjonczyk at biol.uw.edu.pl]

Dear List Members,

in limma manual is stated that 
"A zero weight indicates that the spot should be ignored in all analysis as
being unreliable".
lmFit function uses information from weights.
Is that means that zero-weight spots will not be used in functions:
contrasts.fit, eBayes, decideTests and topTable? I.e. is zero-weight spot
treated as having missing values for fluorescence in these functions?
