The command language always mimics the current source language being
debugged, defaulting to C; C doesn't have a string type.  That's the
historical justification anyway.

If there's a consensus that a string type would be useful, it could
probably be done.  I think it might be a good idea; we could use
strings for arguments to gdb commands, etc.  However I'm not sure of
the syntax.

Anyone else out there have an opinion?
