This did used to be true, but should be fixed with the 1.30 release,
since the file indexing uses a different underlying indexing system.
If you have files with failed with the old system (which did have
those limitations) please do check them to be sure they work on
1.30. However (fingers crossed) I do think this has been ironed out.
