+ * With multiple arguments, print names and values of all config items with
+ * matching section names.

+ * With --debug, the source (filename and line number) is printed for each

+ * Options/Argument list option:
+ *
+ *	-u, --untrusted	show untrusted configuration options
+ *	aliases: debugconfigi
+ *
+ * To get showconfig information use the hg_linestream_buffer returned value 
+ * with hg_fetch_line_entry() function.
+ *
+ * \param handle The handle of the connection, wherewith I want to communicate
+ * \param callback A function that will handle error data. 
+ *                 A NULL pointer will ignore error data.
+ * \param argument The option list. Will contain all option that you wish.

+ *                              successful
