	* misc/efgcvt_r.c (fcvt_r): Handle illegal NDIGIT correctly.
	[PR libc/410]
	* misc/Makefile (tests): Add tst-efgcvt.
	* misc/tst-efgcvt.c: New file.

	* manual/arith.texi (Parsing of Integers): Correct description of
	strtoul. Pointed out by Scott Snyder <snyder@fnald0.fnal.gov>.
	[PR libc/396]
	* misc/lsearch.c (lsearch): Return a pointer to the new element
	if one was "allocated".
	* string/strsignal.c: NSIG is not a valid index into
	_sys_siglist.  Don't zap the last character of the "Unknown
	signal" message.
