linelength
How long strings should get before overflowing to next line, for text output.
type: int, default: 128, minimum: 60
Example, where an 80-character long string ("a " * 40) is broken up onto two
lines, when printed as canonical output:
$ echo 'digraph G { linelength=60; N0 [label="a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a "]; }' | dot -Tcanon
digraph G {
graph [linelength=60];
node [label="\N"];
N0 [label="a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a \
a a a a a a a a a a "];
}
The text overflows when the label reaches the given size.
Despite the linelength name, this is the length of the attribute string, not the length of the overall line (which includes the node ID and attribute key).
