	* glib/gkeyfile.c: Add Matthias to "Written by" lines
	 (GKeyFileGroup): add field to hold comments about groups
	 (g_key_file_load_from_fd): return TRUE on success and
	 FALSE on failure.  Don't close fd's opened by other
	 parent function.
	 (g_key_file_load_from_file): run FILE_IS_REGULAR test
	 before trying to open file, to save an fd from being
	 leaked (would probably be better to use fstat()). Close
	 fd when done with it. Return TRUE on success and FALSE
	 on failure.
	 (g_key_file_load_from_data): Return TRUE on success and
	 FALSE on failure.
	 (g_key_file_load_from_data_dirs): remove superfluous
	 const modifier.  Return TRUE on success and FALSE on
	 failure.  Stop trying to load files when one succeeds.
	 (g_key_file_parse_key_value_pair): don't validate input
	 for UTF-8 until users uses a getter that does
	 validation.  Don't leak copy of start_group_name.
	 (g_key_file_to_data): serialize new comment field for
	 groups.
	 (g_key_file_get_keys): Remove convenience code to let
	 NULL group mean start group.  Get rid of unneeded NULL
	 check before g_strdup.
	 (g_key_file_get_groups): Reverse groups list before
	 sending to user because it is maintained in backward
	 order internally.
	 (g_key_file_get_value),
	 (g_key_file_set_value): add g_return checks at top of
	 public functions.
	 (g_key_file_get_string),
	 (g_key_file_get_string_list): validate key value is UTF-8.
	 (g_key_file_[sg]et_*comment): new functions for
	 setting/getting comments
	 (g_key_file_remove_comment): new function to remove
	 comment block
	 (g_key_file_remove_key_value_pair_node): new function to
	 pull a key-value pair out of the list and free it.
	 (g_key_file_remove_group_node): call
	 g_key_file_remove_key_value_pair_node instead of
	 freeing the list immediately to get better statistics
	 for approximate_size.
	 (g_key_file_remove_group): use lookup_group_node instead
	 of lookup_group to prevent a g_list_find call.
	 (g_key_file_add_key): report group also when unable to
	 find key.
	 (g_key_file_lookup_group_node): new function to make
	 getting the group node from a group name easier.
	 (g_key_file_lookup_group): use lookup_group_node under
	 the hood.
	 (g_key_file_lookup_key_value_pair_node): new function to
	 make getting the key-value pair from a group and key
	 name eaiser.
	 (g_key_file_parse_comment_as_value): new function to add '#' to the
	 beginning of every line.
	 (g_key_file_parse_value_as_comment): new function that
	 attempts to be the inverse of comment as value.
