regression: newlines embedded in quoted labels / node names are not preserved in 2.46.0
Steps to reproduce
The following graph produces different output on 2.46.0 than 2.44.1
graph {
node1 [label="line 1
line 2
"];
node2 [label="line 3
line4"];
node1 -- node2
node2 -- "line 5
line 6"
}
I don't see anything in the changelog that would lead me to expect this (although #165 (closed) might be related)
Expected Behaviour
I would expect these labels to continue to have multiple lines, although http://www.graphviz.org/doc/info/attrs.html#k:escString isn't clear on the behaviour.
If this was an intentional change in behaviour, then an update to documentation and mention in the changelog would be warranted.
Actual Behaviour
The lines have been concatenated.
