This escaping requirement was previously leaking into the implementation
of
graph.go
, by writing\n
directly instead of "\n". This meant thatif it was displayed in a different program besides
dot
, it would havebeen potentially incorrectly escaped.
Now, this commit moves all the escaping directly into dotgraph, which is
more encapsulated, and also allows us to escape other characters in the
name which need escaping.
This required adding a justify option to escapeForDot to preserve old behavior.
This allows tag newlines to stay center justified, and legend label
newlines to stay left justified, as they were before we started escaping
them for Dot.
