Multiline developer comments in Qt Linguist

Qt Linguist has  the "Developer comments" field where the comments in C++ source diplayed when the comments are writen in a certain format.
(See "Translator Comments" https://doc.qt.io/qt-5/i18n-source-translation.html#translator-comments )

Some users want to add a multi-lines comment there.However it is not possible at the moment because Qt Linguist formats the comments into a single line as the result. In detail, ASCII characters such as '[escape character]t', '[escape character]n', '[escape character]v', '[escape character]f', '[escape character]r', and ' ' (single space) are trimmed internally by Qt Linguist.

This feature request is to ask enabling Qt Linguist display the multi-lines developer comments as it is.

For example:
Assuming comments are added in the source code as follows:

//: This is a general comment with explains the text.
//: %1 = explanation for the first argument.
//: %2 = explanation for the second argument.
//: %3 = explanation for the third argument.
const char* string = QT_TR_NOOP("%1 is translatable because %2, also %3"); 

At the moment, Qt Linguist displays this as a single-line Developer comments like :

This is a general comment with explains the text. %1 = explanation for the first argument. %2 = explanation for the second argument. %3 = explanation for the third argument.

If this feature request is implemented, this will appear in the Developer comments field as below:

This is a general comment with explains the text.
%1 = explanation for the first argument.
%2 = explanation for the second argument.
%3 = explanation for the third argument.
