using '_.' to indicate table headers doesn't work in SRC v1.160

[Stephen Bannasch]

I'm using" superredcloth (1.160)

Using '_.' to indicate table headers doesn't work:

$ irb
irb(main):001:0> require 'superredcloth'
=> true
irb(main):005:0> SuperRedCloth.new("|_. name |_. age |_. sex |\n| 
joan | 24 | f |\n| archie | 29 | m |\n| bella | 45 | f |\n").to_html
=> "<table>\n\t\t<tr>\n\t\t\t<td>_. name </td>\n\t\t\t<td>_. age 
</td>\n\t\t\t<td>_. sex </td>\n\t\t</tr>\n\t\t<tr>\n\t\t\t<td> joan 
</td>\n\t\t\t<td> 24 </td>\n\t\t\t<td> f 
</td>\n\t\t</tr>\n\t\t<tr>\n\t\t\t<td> archie </td>\n\t\t\t<td> 29 
</td>\n\t\t\t<td> m </td>\n\t\t</tr>\n\t\t<tr>\n\t\t\t<td> bella 
</td>\n\t\t\t<td> 45 </td>\n\t\t\t<td> f </td>\n\t\t</tr>\n\t</table>"

irb(main):006:0> SuperRedCloth.new("|name |age |sex |\n| joan | 24 | 
f |\n| archie | 29 | m |\n| bella | 45 | f |\n").to_html
=> "<table>\n\t\t<tr>\n\t\t\t<td>name </td>\n\t\t\t<td>age
