'_' is also reserved for matching, so that can't be it.
Maybe a better question is: Why doesn't GRASS distinguish between tables
and files (database)? I would much prefer to have GRASS automatically
substitute '_' for '.' in the table name so I can keep consistent naming
conventions across rasters and vectors. It's a usability issue and
somewhat annoying. :-)
I guess the real question is: How big of a job would this be? Radim?
If it isn't an overwhelming job, I'd like to propose it for 7.x.
