Details:

Saving an anonymous function fails whenever symbol_table::current_context ()
is nonzero. I have attached a script which exhibits this functionality.

save_test (1)

fails as it is called when current_context is nonzero but

save_test (0)

works as current_context is zero.

I have also attached a patch that fixes this issue in addition to adding a
test case. The fix is to call varval (0) when saving the variables of an
anonymous function. This causes the anonymous function's variables to
correctly be accessed from context 0, instead of the current_context.

I am guessing this bug also appears in any previous release that allows for
anonymous functions to be saved, but I have not checked.
