The $host_data variable is used when a match in a host list in an ACL
happens as a result of a lookup. The data that was retrieved as part of
the lookup is placed in $host_data. It does *not* contain the item from
the list that was matched. Example:
hosts = net-lsearch;/some/file
If the file contained:
10.0.0.1: this-is-data
then when "hosts" has matched 10.0.0.1, $host_data contains
"this-is-data". There is no variable that contains
"net-lsearch;/some/file".

If $host_data were extended to apply to ${if match_host then it should
be the same as it is in an ACL, so no, it couldn't be the element of the
list that matched.
