Layout of ticket replies in RT

Hello,

Using RT 4.0.10 without WYSIWYG editor.

I have two questions concerning the layout of ticket replies in RT.

When quoting an already quoted part of a message, RT seems to add a
space between the ‘>’ quoting character.
Can this space be disabled somewhere?

The second thing that happens is that line breaks get introduced, which
gets a single ‘>’ quoting character.
Can these line breaks be disabled and or the missing ‘>’ quoting
character be fixed somewhere?

here an example how it looks when hitting reply

Bert,

This a test line, test line, test line, test line, test line, test
line,
test line

This a test line, test line, test line, test line, test line, test
line,
test line

Ideally it would look like;

Bert,

This a test line, test line, test line, test line, test line, test
line, test line

This a test line, test line, test line, test line, test line, test
line, test line

Gr, Justin
