Function call without indentation

[edemaine]

The following examples currently end up calling x as a function, despite the lack of indentation:

x
y: z

x
{y: z}

x
{y: z} = obj

[STRd6]

Also:

x
[y]

Ha, this bug is actually #272 in disguise. The raw output of Civet is actually what we thought it should be:

Civet 0.5.51 REPL.  Enter a blank line to transpile code.
🐈> x
... y: z
...
x
({y: z})
🐈> x
... {y: z}
...
x
({y: z})
🐈> x
... [y]
...
x
[y]
🐈>

The issue is that the Playground runs Prettier, and because this code doesn't trigger automatic semicolon insertion, it gets combined into a function call / property access. So #277 fixes this issue too.
