[Libreoffice] Calc : add carriage return via Ctrl+Enter in the "Formula bar"

Hello

I have been ask to add the possibility to add a carriage return in a
cell via Ctrl+Enter in the formula bar (like when I directly edit the
cell).

#################

Currently, when I edit a cell (directly, not via the formula bar) and
type "test(Ctrl+Enter)test" I get this cell :
 _______
|test   |
|test___|

When I edit a cell via the formula bar and try to type the same thing I
leave the formula when I type Ctrl+Enter.

What I have been asked :
Same behavior in the formula bar and the cell. When I edit a cell via
the formula bar and type "test(Ctrl+Enter)test" I get this cell :
 _______
|test   |
|test___|

#################

Before starting to code or even look if it's possible and how many time
it will take (I am a beginner at LibreOffice development) I would like
to know if this feature have chance to be accepted ?

Thanks in advance
