In apache 0.8.7 and 0.8.8 (and earlier versions), for a parsed html file
containing a <!--#exec cmd -->

PATH_INFO was set, even if NULL.
If PATH_INFO was unset, PATH_TRANSLATED was set to the directory containing
the shtml file.
PATH_TRANSLATED might not contain all the translated path.
e.g. if the URL was /test.shtml/index.html/wibble
then PATH_INFO would be /index.html/wibble
but PATH_TRANSLATED would only be /docroot/index.html
If the URL contains encoded '%' characters then PATH_TRANSLATED might
be incorrect.

Fix: copy the code for setting PATH_INFO and PATH_TRANSLATED from
mod_cgi.c to mod_include.c, replacing the code in include_cmd_child.
This guarantees that the two methods of invoking CGI scripts are
(bug for bug) compatible.
