[REVIEW 3-6 3-5] fdo#36138: sd: fix undo in text objects

[Ivan Timofeev]

Hi,

I have fixed
  https://bugs.freedesktop.org/show_bug.cgi?id=36138
using my ultimate clumsy technique: try to change something somehow and 
see if that helps.

http://cgit.freedesktop.org/libreoffice/core/commit/?id=c6fdd2e4e5a54b388d25ca0fc97e1f325ae7a566

That SidArray is passed to SfxBindings::Invalidate in FuText::KeyInput.

If this is a good fix, please cherry-pick to 3-6 and 3-5.

Thanks a lot,

Ivan
