Fix Breaks commit.

Enable depisok for the Breaks case. Remove comments stating Breaks needs to
be implemented. And split functions calls which had different arguments
depending on a variable.

+	* src/cleanup.c (cu_prermdeconfigure): Split call to
+	maintainer_script_installed depending on the conflictor variable.
+	* src/packages.c (dependencies_ok): Remove comment stating that
+	Breaks needs to be implemented.
+	* src/depcon.c (depisok): Likewise. Remove return at the beggining
+	of the function checking for a Breaks dependency, that was
+	efectively making it a no-op in that case.
+	* src/processarc.c (process_archive): Fix indentation. Split calls
+	in deconfigure code to printf and maintainer_script_installed
