editor: ignore added or copied files excluded by a filemap Files brought by a copied add_directory() were processed despite being excluded by the filemap. This was also the case with added files. The conversion was still correct because they were eventually filtered out in the replay.convert_rev() but processing them in itself may be problematic. Filemaps are often use to exclude large binary files and before this change, some of them could be marked as missing and be fetched before being discarded. A test configuration entry named hgsubversion.failoninvalidreplayfile was added to help testing this case. It should become the default behaviour in the future.
