Merge union order

[Cédric Krier]

Hi,

In our repository we are filling a CHANGELOG text file when developing
new feature. The rule is to append on top of the file new entries.
The problem is that obviously we have very often merge conflict with
that file. So in order to simplify the merge process, I though about
using `internal:union` tool. This works great but instead of having the
new entry on top, it is merged at the bottom of the conflict.
So is there a way to tell `internal:union` to unify the other way?

Thanks,
