```
The MERGE_HEAD ref is not available in the pre-merge-commit hook, but
it is available in subsequent hooks prepare-commit-msg and commit-msg

From https://github.com/git/git/blob/master/builtin/merge.c#L843 :
in prepare_to_commit() the call to write_merge_heads() is after
run_commit_hook("pre-merge-commit")

Can the write_merge_heads() call be moved up? At first glance it
doesn't look like it would break anything.

```
