Whitespace in multiline string literals inconsistent with outside

[ysangkok]

I added the following to markdown/Source.md:

str : String
str =
  """
    Didn't expect the whitespace and the brackets to be considered data
    constructors. The whitespace at the beginning of each line isn't
    significant, so I'd think it wouldn't get highlighted.
    \{ show (1 + 1) }
    Also expected the whitespace inside the snippet to have the same highlight as
    the whitespace outside (none at all).
  """
  <+> show (1 + 1)

Here is a sample of the unexpected whitespace and bracket getting highlighted as a data constructor:

<span class="IdrisData">&nbsp;&nbsp;&nbsp;&nbsp;\\{&nbsp;</span>
