Generates invalid labels for rail signals enabled for both read and close

[JC3]

Latest version of graphviz tools choke on the labels generated for rail signals that have both the "read signal" and "close signal" mode enabled:

Error: bad label format {rail-signal|{Red Signal|signal-red}|{Orange Signal|signal-yellow}|{Green Signal|signal-green}{inserter|<|0}}

Here is a sample blueprint:

Here is the graphviz file generated:

graph combinators {
graph[overlap="portho" splines="spline" sep=0.5];
332705 [shape=record label="<1>\>|{decider-combinator|{nil|\<|0}|{nil|=input}}|<2>\>" pos="19,-539"];
332705:2 -- 332703:1 [color=red headport=_ tailport=e];
332703 [shape=record label="{rail-signal|{small-lamp|\<|0}}" pos="21,-539"];
332703:1 -- 332710:1 [color=red headport=_ tailport=_];
332710 [shape=record label="{rail-signal|{Red Signal|signal-red}|{Orange Signal|signal-yellow}|{Green Signal|signal-green}{inserter|\<|0}}" pos="24,-539"];
332706 [shape=record label="{rail-signal|{Red Signal|signal-red}|{Orange Signal|signal-yellow}|{Green Signal|signal-green}}" pos="21,-536"];
332706:1 -- 332707:1 [color=green headport=_ tailport=_];
332707 [shape=record label="{rail-chain-signal|{Red Signal|signal-red}|{Orange Signal|signal-yellow}|{Green Signal|signal-green}|{Blue Signal|signal-blue}}" pos="24,-536"];
332707:1 -- 332708:1 [color=green headport=w tailport=_];
332708 [shape=record label="<1>\>|{decider-combinator|{nil|\<|0}|{nil|=input}}|<2>\>" pos="27,-536"];
}

I'm not entirely familiar with graphviz label formats but my gut says there's a missing | between the read and write {...} things.
