Patch for ob-sql.el SQL output

[Charles Sebold <csebold@gmail.com>]

I use org-mode and babel under Windows with osql, and the line
separating the header from the rest of the rows in the output was
bothering me.

I don't know that this is a really good fix, but maybe it's a start
for one?  I've filled out paperwork with FSF for copyright assignment.
 It looks for the first output line of all dashes and replaces it
later with the 'hline when the table is lisp-ified.  I didn't test
this with mysql or postgresql.
