[PATCH] why is '-' not allowed in radio table name?

[Dan Davison <davison@stats.ox.ac.uk>]

I was using a radio table to convert an org table to texinfo, and got
stuck for a bit until looking at the code and seeing that the name used
for the radio table can not contain '-' (only letters, numbers and
underscore). Is there a reason for this restriction? An alternative
regexp is below (which also allows tabs as whitespace).
