[ns] [patch] cmu-trace.cc in NS-2.1b8

[Daichi Furusaka <furu@ht.sfc.keio.ac.jp>]

Hi all,

I have attached a small patch for NS-2.1b8 which addresses
invalid nam trace format of NAM-1.0a10.

ns-ver:	2.1b8
nam-ve:	1.0a10
OS:	FreeBSD 4.3R
problem:when using nam for visualization of wireless
	simulation, nam said the following warning.

	> Unexpected end of line in: <%s:NAM_TRACE_FORMAT>
	> Perhaps you have extra spaces at the end of the line.

file:	$NS/cmu-trace.cc
solution:
	- corrects extra spaces at EOL of nam trace.
	- this patch (diff -p) is attached to this mail.

Also I can find another invalid format in "$NS/tcl/lib/ns-lib.tcl".
In "Simulator instproc initial_node_pos {nodep size}", ns puts
nam-configuration with `-z' option which is an unknown flag.
But I guess this is an incoming option or something.
So nothing has been done with it.

# Maybe it seems to be better for waiting that wireless nam options
# are fixed.
