ACS bug in pvt/home.tcl?

So, I just implemented a little bit of PS3, and I noticed that the help links to the content section help topics were not working. Upon inspection, I saw the following code in pvt/home.tcl:

set selection [ns_db select $db "select section_url_stub, 
section_pretty_name, sort_key, intro_blurb, help_blurb
from content_sections
where enabled_p = 't'
order by sort_key, upper(section_pretty_name)"]

set last_sort_key ""
while { [ns_db getrow $db $selection] } {
    set_variables_after_query
    if { ![empty_string_p $last_sort_key] && ($last_sort_key != 
$sort_key) } {
        append content_section_items "
\n"
    }
    set last_sort_key $sort_key
    append content_section_items "<li><a 
href=\"$section_url_stub\">$section_pretty_name</a>\n"
    if ![empty_string_p $intro_blurb] {
        append content_section_items " - $intro_blurb"
    }
    if ![empty_string_p $help_blurb] {
        append content_section_items " <font size=-1><a 
href=\"content-help.tcl?[export_url_vars section_key]
\">help</a></font>"
    }
}

Notice that the help link (content-help.tcl) references the url variable section_key, which is nowhere to be found. It's not in the SELECT; section_key is just another column in the table. Easy fix, just add it to the select:

set selection [ns_db select $db "select section_key, 
section_url_stub, section_pretty_name, sort_key, intro_blurb, 
help_blurb
from content_sections
where enabled_p = 't'
order by sort_key, upper(section_pretty_name)"]
