If you mean something like
that won't work, because the \ is not interpreted by FileCheck.  It is
doing a very dumb scan for the sequence }} and not attempting to parse or
interpret whatever is in between.  I think it's easy enough to add the
parentheses to break up unintended sequences of braces.

Committed r367689 to add the parens suggestion to the FileCheck doc.
