Golang: Missing semicolons not properly induced

[nicoberling]

The parser currently doesn't induce semicolons correctly: The statementList

i := a
+b

is parsed as a single line i := a + b: but a semicolon should have been inserted after the identifier a, giving

i := a;
+b;

where the second statement would give us an error in Go because the value is never used, but is syntactically correct, and should get parsed.
