	Document namespace sigc briefly

	* sigc++/signal_base.h (sigc): Prepend documentation comment to
	provide a brief description of namespace sigc, so that Doxygen

	Protect space after comma in M4 output

	* sigc++/macros/template.macros.m4 (_LOOP_SEP): Triple-quote the
	list separator in this hairy construct, since the macro definition
	itself is not quoted at all and the space after the comma got lost
	in the output.  This, in turn, produced overlong lines in the HTML
	reference documentation.
