have "line wrap" turned on for freshly merged cells standardly


reason: if the case occurs where line wrap would be of use and one doesn't use 
it, one wouldn't have to merge the cells, beacuse one can't use the cell for 
any other purpose now cause it contains text but the text is just in one line, 
so the other merged cells don't serve any purpose and could as well be ummerged.
wait: merging 2 cells vertically and centering text vertically and using mre 
text than the cells are wide. but then: obviously if the text should be 
readable the adjacent cells must be empty; so why haven't they been merged in 
teh first place too so that the merged cell is wide enough?

ergo: have "line wrap" turned on for freshly merged cells standardly
