While I'm not very enthusiastic on backporting all fixes to a 3.4.x
branch as the code is diverging significantly,
I'm creating the branch at least, to make the option available to
evaluate backporting on a per-case basis, especially if anybody
volunteers to pick & port the commit.
I'm going to apply HSEARCH-744 on such a branch as it was nicely fixed
by Mathieu Perez, and it was flagged for a fix in 3.4.1.
