Changes by:	zkabelac@sourceware.org	2009-11-03 11:00:47

Modified files:
	lib/format_text: export.c text_export.h 

Log message:
	Export functions out_inc_indent(), out_dec_indent() for creating
	indented metadata lines.
	
	Macro outnl() is using exported out_newline() instead of direct
	call f->fn(), that required the visibility of the internal
	struct formatter.
