Fix for tdf#82744: on gerrit, patch was split

[Giuseppe Castagno]

Hi all,

I finished the testing, then I split the fix in three patches.

First is at:

https://gerrit.libreoffice.org/#/c/17080

Reviewers would be welcome.

BTW, I added a short line here:

https://wiki.documentfoundation.org/Development/gerrit/SubmitPatch

explaining the line length limits in commit subject and comment message.
I didn't find it explained anywhere else.

Tnx
