Oh, thanks for pointing this out, I've just pushed up a fix.  The single
"-" was tricking the number checker because it looks like a minus sign
about to be followed by numbers.  These characters are no longer
converted to 0s.

Users may want to insert a "-" in their tables, and I think it would be
surprising to magically replace floating "-" characters with hlines.
There are numerous existing options for inserting hlines into tables,
e.g., the :colnames header argument, using the raw, wrap and org result
types and printing literal Org-mode syntax from your block, additionally
any result could be passed through an elisp code block which may insert
hline symbols at will.

Is there a specific use case which isn't addressed by the existing
functionality?

Thanks,
