#2790 [puts] accepts invalid arguments

[Joe Mistachkin]

To duplicate:

puts stdout "this is a test." ""

Please note the extra set of double quotes after the
string.

Line 105 of tclIOCmd.c is currently:

if (strncmp(arg, "nonewline", (size_t) length) != 0) {

I believe It SHOULD be:

if (length > 0 && strncmp(arg, "nonewline", (size_t)
length) != 0) {

Oops! What I meant to say was that the line should be:

if (length == 0 || strncmp(arg, "nonewline", (size_t) length) !
= 0) {

Commited the fix to 8.4 and head. small modification:
Checking for length != 9, to accept only "nonewline", and no
abbreviation.
