Note that the same typo (handle_sample_event) appears in the other two
LTL golden files added in patch 05/17 as well: ltl_pertask.c and
test_ltl.c. The root is likely in the rvgen LTL template itself, so
the fix there would regenerate all three consistently.

Understood on the intent. One small concern:  MODULE_AUTHOR(/* TODO */)
is subtly different from an XXX comment — a C preprocessor strips the
comment before macro expansion, leaving  MODULE_AUTHOR() with an empty
argument. When the user does go to compile, they get a cryptic error
rather than a clear "fill this in" hint.
