Sure, dcraw_emu appends .tiff or .ppm to existing image filename.
This is very useful if someone (e.g. me) uses both dcraw and dcraw_emu in parallel (for example, for results comparsion): one program does not overwrites results of another one.
Also, if you have both DSCF0001.ARW a DSCF0001.NEF (from Sony and Nikon, respectively), 'dcraw DSCF0001.*' will produce only one resulting file, while dcraw_emu will save both results in separate files.
