Cleanup weird cases where the parser would
bump()
interior nodes into the output stream rather thanemit()
ing them. Emitting all interior nodes explicitly means we can remove some special cases which occurred during tree building.As part of this, fix some errors converting broken expressions like
x var"y"
fromSyntaxNode
toExpr
.Fixes #330
