[Libreoffice] [PATCH] run-libreoffice-ciabot: avoid flood on merges

[Miklos Vajna]

Hi Kendy,

I'm attaching a patch that updates the cia bot so that you don't need to
manually disable it on each merge. ;)

OK to push? (More importantly, if I push it, it would be nice if you
could restart the bot, as I guess that's not automatic. :) )

Thanks.

Subject: [PATCH] run-libreoffice-ciabot: avoid flood on merges

Check if the last hash is a merge commit: if yes, then just announce the
last one, otherwise do the usual "announce any commit since the last
one" dance.
