Force br newlines on reply

[joosty]

Just installed latest 0.4 version of Roundcube and applied the steps mentioned at TinyMCE:Configuration/force br newlines - Moxiecode Documentation Wiki to have a normal line break after hitting enter.

This works fine while composing new HTML emails, but when I reply to an HTML mail, the behaviour is unchanged: hitting enter results in a new paragraph instead of a new line.

Any advice?
