Added a new element (STACKED) to EEControlBits. It would be better to use only ONECHARPERLINE, but calc and impress used it from different places, and couldn't recognise each other, so they may overwrite each other. With this fix they both set a separate flag, and editeng check if any of the flags are set. regression was made by: I535da45e3a2f2d1550bad2a40e9909e0d561d0ef Change-Id: I60496059f3ce2773b232970bf2c3b7264ce64c5b Reviewed-on: https://gerrit.libreoffice.org/c/core/+/163682 Tested-by: Jenkins Reviewed-by: Caolán McNamara <caolan.mcnamara@collabora.com>
