I use both underscores and dashes without paying close attention. If I'm
typing quickly I'll use the dash because it does not require the shift key.
But, your point is well taken.

The data display properly, even with dashes in directory and file names.
I've no idea about possible glitches in r.in.gdal or some other place within
