Syntax errors when forgetting an end are annoying to debug

[Dekkonot]

In the case that you forget an end somewhere in a Lua file, the error emitted by Full Moon makes it difficult to diagnose where the end should have been. It will say that it encountered an "unexpected token ``" at the end of the file and then list the expected token (an end), without specifying where the end is expected from. For files that are hundreds or potentially thousands of lines long, this can be problematic for what should hopefully be obvious reasons.

Is this mostly selene issue?

For:

function add(a, b)
  return a + b

selene (version 0.8.0) reports:

error[parse_error]: unexpected token ``

   ┌── /Users/zummenix/projects/full-moon/full-moon/tests/cases/fail/parser/missing-end/source.lua:4:1 ───

Yep--I think there's an issue outstanding for it.
