Bug 145058 - Inputting "^^" requires four keystrokes on Win32, differs

	Bug 145058 - Inputting "^^" requires four keystrokes on Win32,
	differs from platform default behaviour

	* gtk/gtkimcontextsimple.c
	(check_win32_special_case_after_compact_match): New
	function. Called from check_compact_table() after a table-based
	match has committed a character. In case there was two identical
	dead accents in the input, another copy of the spacing accent that
	was already committed is committed. This fixes #145058.

	(check_win32_special_cases): New function. Called first from
	gtk_im_context_simple_filter_keypress(). This fixes another
	problem: a dead accent followed by a space should commit the
	corresponding spacing accent. The compose tables from X commit
	another character in two cases and we want to override that on
	Windows.

	Add GTK_NOTE (MISC) debugging output to this code.
