[Libreoffice] [PATCH] Clean-up of bugfix fdo#32895 for the -3-4 branch

[Péter Rabi]

Hi Michael, *

I attached the patches that fix bug fdo#32895. I eliminated the baroque
castings and reused the duplicated function as you suggested.

A review and push to the -3-4 branch would be highly appreciated.

Best regards,
  Péter
