Removed obsolete commented-out lines from fe_cleanup() so the function no longer contains dead commented code.

Removed an unnecessary explanatory comment above the unconditional early return in log_handler(), leaving only the active behavior.

Removed an unneeded section marker comment before fe_idle() to keep surrounding code cleaner.
