- *
- * Revision 1.29 2002/04/26 19:30:54 jongfoster
- * - current_action_to_html(): Adding help link for the "-" form of
- * one-string actions.
- * - Some actions had "<br>-", some "<br> -" (note the space).
- * Standardizing on no space.
- * - Greatly simplifying some of the code by using string_join()
- * where appropriate.
- *
- * Revision 1.28 2002/04/26 12:53:15 oes
- * - CGI AF editor now writes action lines split into
- * single lines with line continuation

- *
- * Revision 1.26 2002/03/26 22:29:54 swa
- * we have a new homepage!
- *
- * Revision 1.25 2002/03/24 13:25:43 swa
- * name change related issues
- *
- * Revision 1.24 2002/03/16 23:54:06 jongfoster
- * Adding graceful termination feature, to help look for memory leaks.
- * If you enable this (which, by design, has to be done by hand
- * editing config.h) and then go to http://i.j.b/die, then the program
- * will exit cleanly after the *next* request. It should free all the
- * memory that was used.
- *
- * Revision 1.23 2002/03/07 03:46:16 oes
- * Fixed compiler warnings
- *
- * Revision 1.22 2002/01/21 00:27:02 jongfoster
- * Allowing free_action(NULL).
- * Moving the functions that #include actionlist.h to the end of the file,
- * because the Visual C++ 97 debugger gets extremely confused if you try
- * to debug any code that comes after them in the file.
- *
- * Revision 1.21 2002/01/17 20:54:44 jongfoster
- * Renaming free_url to free_url_spec, since it frees a struct url_spec.
- *
- * Revision 1.20 2001/11/22 21:56:49 jongfoster
- * Making action_spec->flags into an unsigned long rather than just an
- * unsigned int.
- * Fixing a bug in the display of -add-header and -wafer
- *
- * Revision 1.19 2001/11/13 00:14:07 jongfoster
- * Fixing stupid bug now I've figured out what || means.
- * (It always returns 0 or 1, not one of it's paramaters.)
- *
- * Revision 1.18 2001/11/07 00:06:06 steudten
- * Add line number in error output for lineparsing for
- * actionsfile.
- *
- * Revision 1.17 2001/10/25 03:40:47 david__schmidt
- * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
- * threads to call select() simultaneously. So, it's time to do a real, live,
- * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
- * (native). Both versions will work, but using __OS2__ offers multi-threading.
- *
- * Revision 1.16 2001/10/23 21:30:30 jongfoster
- * Adding error-checking to selected functions.
- *
- * Revision 1.15 2001/10/14 21:58:22 jongfoster
- * Adding support for the CGI-based editor:
- * - Exported get_actions()
- * - Added new function free_alias_list()
- * - Added support for {{settings}} and {{description}} blocks
- * in the actions file. They are currently ignored.
- * - Added restriction to only one {{alias}} block which must appear
- * first in the file, to simplify the editor's rewriting rules.
- * - Note that load_actions_file() is no longer used by the CGI-based
- * editor, but some of the other routines in this file are.
- *
- * Revision 1.14 2001/09/22 16:36:59 jongfoster
- * Removing unused parameter fs from read_config_line()
- *
- * Revision 1.13 2001/09/16 15:47:37 jongfoster
- * First version of CGI-based edit interface. This is very much a
- * work-in-progress, and you can't actually use it to edit anything
- * yet. You must #define FEATURE_CGI_EDIT_ACTIONS for these changes
- * to have any effect.
- *
- * Revision 1.12 2001/09/16 13:21:27 jongfoster
- * Changes to use new list functions.
- *
- * Revision 1.11 2001/09/14 00:17:32 jongfoster
- * Tidying up memory allocation. New function init_action().
- *
- * Revision 1.10 2001/09/10 10:14:34 oes
- * Removing unused variable
- *
- * Revision 1.9 2001/07/30 22:08:36 jongfoster
- * Tidying up #defines:
- * - All feature #defines are now of the form FEATURE_xxx
- * - Permanently turned off WIN_GUI_EDIT
- * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
- *
- * Revision 1.8 2001/06/29 13:19:52 oes
- * Removed logentry from cancelled commit
- *
- * Revision 1.7 2001/06/09 10:55:28 jongfoster
- * Changing BUFSIZ ==> BUFFER_SIZE
- *
- * Revision 1.6 2001/06/07 23:04:34 jongfoster
- * Made get_actions() static.
- *
- * Revision 1.5 2001/06/03 19:11:48 oes
- * adapted to new enlist_unique arg format
- *
- * Revision 1.4 2001/06/01 20:03:42 jongfoster
- * Better memory management - current_action->strings[] now
- * contains copies of the strings, not the original.
- *
- * Revision 1.3 2001/06/01 18:49:17 jongfoster
- * Replaced "list_share" with "list" - the tiny memory gain was not
- * worth the extra complexity.
- *
- * Revision 1.2 2001/05/31 21:40:00 jongfoster
- * Removing some commented out, obsolete blocks of code.
- *
- * Revision 1.1 2001/05/31 21:16:46 jongfoster
