IMHO it works quite right and the observed behaviour is correct.
As the contents within double-quotes is seen as one element, you get it
back as one list element. A recent csv should also preserve the
newlines, so you should get:
1 2 3 4 {a b c
d e f
g h i j
k l m}

To transform the abc- etc part to a matrix, I would do:
% set listIn {1 2 3 4 {a b c
d e f
g h i j
k l m}}
% set matrixRaw [lindex $listIn 4]
{a b c
d e f
g h i j
k l m}
% set matrixOut {}
% foreach rowRaw [split $matrixRaw "\n"] {
	lappend matrixOut [split $rowRaw " "]
}
% set matrixOut
{{abc} {d e f} {g h i j} {k l m}}

Hope this helps,
Harald
