	attempts [Coverity CID 67].

	* io/fts.c (fts_build): Comment out dead code [Coverity CID 68].

	* sunrpc/rpc_parse.c (def_union): Comment out dead code
	[Coverity CID 70].

	* locale/programs/linereader.c (lr_token): Remove duplicate
	handling of EOF [Coverity CID 71].

	* locale/programs/ld-numeric.c (numeric_read) [case tok_grouping]:
	We bail out early if ignore_content is set, so there is no need to
	check it later again [Coverity CID 72].
