merge-file doc: set conflict-marker-size attribute

From: Phillip Wood <[email protected]>

When committing a conflict resolution for a merge containing 1f010d6bdf7 (doc: use .adoc extension for AsciiDoc files, 2025-01-20) my pre-commit hook failed because "git diff --check" thought there was a left over conflict marker in "merge-file.adoc". Fix this by setting the "conflict-marker-size" attribute as we do for all the other documentation files that contain example conflict markers.

merge-file doc: set conflict-marker-size attribute

Grepping around I can't find any other files with conflict markers without this attribute set. (If there were I think my pre-commit hook would have complained about them as well)

Well spotted. "git grep -n '^<<<<<<<'" tells me that the git-merge-file, git-merge, and user-manual require them, but this was a rather old line dating back from 2008, so it is a bit surprising nobody caught it before.

Will queue. Thanks.
