DT_SINGLELINE Displays text on a single line only. Carriage

Setting DT_SINGLELINE would prohibit to use custom line breaks.
if WordWrap=false then label should be in one line (eq. singleline),
calculate rectangle should care about it,
when not DT_SINGLELINE include, draw text is use more complicated part.
tLabel in most cases is single line
We have three cases:
1. single line,
2. multiple line divide by carriage return
3. multiple line divide by carriage return and anywhere - when is
not insufficient place
in tLabel we have only WordWrap property, for me its not the same
like dt_wordWrap only differ from single and multiple line,
tLabel must not difference case 2 and 3, in most cases is the same,
only cases 1 and 3
Why should TLabel ignore user's line breaks when WordWrap=false?
Do you think, it is this too complicated for the widgetsets?
This patch seems to be applied in 8956, but it breaks expected
behaviour, see http://www.lazarus.freepascal.org/mantis/view.php?id=1964.
Can I revert that patch?
IMHO, the user can make a difference between 1 and 2 by adding
LineEndings in its text and between 1 and 3 by setting WordWrap to true.
Note that AutoSize won't enlarged the width of label, unless the longest
word doesn't fit, if you set WordWrap to true.
I have taken a better look and I propose this patch:
