tdf#144107: fix incorrect conditioning on bGrid...

introduced in 3092322bb83998397b09d3f34b6d04b5e5c1da50

The intention was to avoid the default line drawing in the original else
branches to be conditional on bMergeCover. The previous patch used
'bGrid' as a surrogate for the original 'else' case - which is wrong.
