2dlabels ignores newline \n

[Elaine Meng]

Example:
2d create lab color orange text 'phosphorylated \n (activated)'

... doesn't put the \n in the label but also doesn't make a newline.

Definitely low-priority since the workaround is just to make a separate label for each line. Only reporting this since it's documented to work. I can remove that sentence from the documentation if you think it best.
