+ *    Revision 1.8  2001/06/29 13:21:46  oes
+ *    - Cosmetics: renamed and reordered functions, variables,
+ *      texts, improved comments  etc
+ *
+ *    - Removed ij_untrusted_url() The relevant
+ *      info is now part of the "untrusted" page,
+ *      which is generated by filters.c:trust_url()
+ *
+ *    - Generators of content now call finish_http_response()
+ *      themselves, making jcc.c:chat() a little less
+ *      cluttered
+ *
+ *    - Removed obsolete "Pragma: no-cache" from our headers
+ *
+ *    - http_responses now know their head length
+ *
+ *    - fill_template now uses the new interface to pcrs, so that
+ *       - long jobs (like whole files) no longer have to be assembled
+ *         in a fixed size buffer
+ *       - the new T (trivial) option is used, and the replacement may
+ *         contain Perl syntax backrefs without confusing pcrs
+ *
+ *    - Introduced default_exports() which generates a set of exports
+ *      common to all CGIs and other content generators
+ *
+ *    - Introduced convenience function map_block_killer()
+ *
+ *    - Introduced convenience function make_menu()
+ *
+ *    - Introduced CGI-like function error_response() which generates
+ *      the "No such domain" and "Connect failed" messages using the
+ *      CGI platform
+ *
+ *    - cgi_show_url_info:
+ *      - adapted to new CGI features
+ *      - form and answers now generated from same template
+ *      - http:// prefix in URL now OK
+ *
+ *    - cgi_show_status:
+ *      - adapted to new CGI features
+ *      - no longer uses csp->init_proxy_args
+ *
+ *    - cgi_default:
+ *      - moved menu generation to make_menu()
+ *
+ *    - add_stats now writes single export map entries instead
+ *      of a fixed string
+ *
+ *    - Moved redirect_url() to filters.c
+ *
+ *    - Fixed mem leak in free_http_response(), map_block_killer(),
+ *
+ *    - Removed logentry from cancelled commit

+ *    - Cleaned up, renamed and reordered functions,
+ *      improved comments
+ *    - Removed my_strsep
+ *    - Replaced globalflag with a general flags int
+ *      that holds PCRS_GLOBAL, PCRS_SUCCESS, and PCRS_TRIVIAL
+ *    - Introduced trivial option that will prevent pcrs
+ *      from honouring backreferences in the substitute,
+ *      which is useful for large substitutes that are
+ *      red in from somewhere and saves the pain of escaping
+ *      the backrefs
+ *    - Introduced convenience function pcrs_free_joblist()
+ *    - Split pcrs_make_job() into pcrs_compile(), which still
+ *      takes a complete s/// comand as argument and parses it,
+ *      and a new function pcrs_make_job, which takes the
+ *      three separate components. This should make for a
+ *      much friendlier frontend.
+ *    - Removed create_pcrs_job() which was useless
+ *    - Fixed a bug in pcrs_execute
+ *    - Success flag is now handled by pcrs instead of user
+ *    - Removed logentry from cancelled commit
