multi-line functions break generateAssertions

[mahrud]

Unless this test was edited manually, I believe at some point generateAssertions supported multiline functions in its input, but now it is broken:

i1 : generateAssertions ///
     f = x -> (
         x + x)
     f(1)
     ///

o1 =
     assert( (try f = x -> ( else oops) === oops );
     assert( (try     x + x) else oops) === oops );
     assert( (try f(1) else oops) === oops );
