$ echo foo | sed 's/ */,/g'
,f,o,o
$

On Solaris and Linux I get ,f,o,o, (which is what I expected).
The following work correctly:

$ echo | sed 's/ */,/g'
,
$ echo foo | sed 's/ *$/,/g'
foo,
$

Here's another (related) bug:

$ echo foo | sed 's/ */,/1'
,foo
$ echo foo | sed 's/ */,/2'
,foo
$ echo foo | sed 's/ */,/3'
,foo
$ echo foo | sed 's/ */,/4'
,foo
$ echo foo | sed 's/ */,/5'
,foo
$ 

Tony.
