When merging file pairs after they have been broken up we queue a new file pair and discard the broken-up ones. The newly-queued file pair reuses one filespec of the broken up pairs each, where the respective other filespec gets discarded. But we only end up freeing the filespec's data, not the filespec itself, and thus leak memory. Fix these leaks by using `free_filespec()` instead.
