Subject: [EXEC] Fixed execing of scripts with no hash-bang

The function tryexec used the original name instead of the path found through
PATH search.  This patch fixes that.

Test case:

	trap 'rm -f $TMP' EXIT
	TMP=$(tempfile -s nosuchthing)

	cat <<- EOF > $TMP
		echo OK
	EOF
	chmod u+x $TMP

	cd /
	PATH=${TMP%/*} ${TMP##*/}

Old result:

	/bin/sh: Can't open filelgY4Fanosuchthing

New result:

	OK
