shm and wal files remain present (Write-Ahead Logging)

[mpd-dude]

Seen in BeyondCompareSQLitePlugin v1.2.1 and BeyondCompare v4.1.3:

• compare the 2 attached db files "test1.db" and "test2.db" with BeyondCompare Text Compare
• test1.db-shm, test1.db-wal, test2.db-shm, test2.db-wal files are created in the same directory
• close BeyondCompare
• *.db-shm files and *.db-wal files are still present. They are not being "merged back" to the main *.db files

Is there some close operation missing? When workign with other sqlite tools like http://sqlitebrowser.org/, for the same db files, the *.db-shm files and *.db-wal files are not present anymore when closing the db files.

Thanks for having a look.

The plugin cannot merge, it will create only a read only view on the diff.
