File.ftype/Pathname causes TruffleRuby error

[deepj]

To reproduce:

ruby -rpathname -e "p File.ftype(Pathname.new('/').realpath)"

Error:

-e:1:in `block (2 levels) in attach_function_eagerly': TruffleRuby doesn't have a case for the org.truffleruby.core.string.StringNodesFactory$StringToNullTerminatedByteArrayNodeFactory$StringToNullTerminatedByteArrayNodeGen node with values of type  Pathname(com.oracle.truffle.object.DynamicObjectBasic) (TypeError)

Notice: I noticed there are two spaces before Pathname(com.oracle.truffle.object.DynamicObjectBasic)

This is fixed at: e1692d2.

@bjfish Could you also fix the "two spaces before" reported above? It seems trivial.

[bjfish]

@eregon Yes, the extra space is removed here: a8263a5
