The `wt printlog` command has trouble finding all the information it needs on its own. The following logs show:
- My shell is in a MongoDB dbpath
- Running `wt printlog` and `wt -h <path> printlog` fail
- Running `wt -C 'log=(path=journal)' works
- Copying files from the `journal` subdirectory into the dbpath also fixes the problem without needing the -C.
