This code was in team/murf/bug8684-trunk; it should fix bug 8684 in trunk. I didn't add it to 1.4 yet, because it's not entirely clear to me if this is a bug fix or an enhancement. A lot of files were affected by small changes like ast_variable_new getting an added arg, for the file name the var was defined in; ast_category_new gets added args of filename and lineno; ast_category and ast_variable structures now record file and lineno for each entry; a list of all #include and #execs in a config file (or any of its inclusions are now kept in the ast_config struct; at save time, each entry is put back into its proper file of origin, in order. #include and #exec directives are folded in properly. Headers indicating that the file was generated, are generated also for each included file. Some changes to main/manager.c to take care of file renaming, via the UpdateConfig command. Multiple inclusions of the same file are handled by exploding these into multiple include files, uniquely named. There's probably more, but I can't remember it right now.

+
+   Also, All #include/#exec statements are recorded in the "includes" LL in the ast_config structure. The file name

+   included in the output files on a file_save operation. 
+
+   The lineno's are really just for relative placement in the file. There is no attempt to make sure that blank lines
+   are included to keep the lineno's the same between input and output. The lineno fields are used mainly to determine
+   the position of the #include and #exec directives. So, blank lines tend to disappear from a read/rewrite operation,
+   and a header gets added.
+
+   vars and category heads are output in the order they are stored in the config file. So, if the software
