Exchange the values of graph->columns and graph->new_columns using the

This transformation was not done by the semantic patch swap.cocci
because there's an unrelated statement between the second and the last
step of the exchange, so it didn't match the expected pattern.

Is it really true that Coccinelle cannot be told to look for a code block
that declares a variable that is then used *only* in the lines we want to
match and replace?

I never used the tool, and a quick web search did not clarify the picture,
either...
