Wrapped lines (multi-line values) with initial whitespace are incorrectly stored

[cvbge]

I have "Wrap lines after escaped newline characters" option enabled.

Following value:

void foo() {
  ++x;
}

should be encoded as: (1)

void foo() {\n\
\  ++x;\n\
}

Notice the initial "\ " in second line - it is added to keep the initial whitespace characters in this line.

But the plugin encodes it as

void foo() {\n\
  ++x;\n\
}

which is invalid because it is decoded as

void foo() {
++x;
}

which is wrong - initial indentation in 2nd line is lost.

Same if I open a file with correct encoding (1), then the plugin displays it correctly, but when it saves it back, it removes the initial "\ ".
