[Bioc-devel] a warning we may not need any more?

*Warning message:*

*In .Seqinfo.mergexy(x, y) :*

*  Each of the 2 combined objects has sequence levels not in the other:*

*  - in 'x': chr4, chr16, chr10, chr11, chr18, chr20, chr22*

*  - in 'y': chrY*

*  Make sure to always combine/compare objects based on the same reference*

*  genome (use suppressWarnings() to suppress this warning).*


*It seems to me that if we can check equality of the assigned genomes, we
should*

*not issue this warning.*
