From: Orgad Shaneh <org...@gmail.com> commit-msg is needed to either validate the commit message or edit it.
Gerrit for instance uses this hook to append its Change-Id footer. The hook is installed on the user's machine, and it is expected to append the footer for each commit that the user creates. This is relevant to merge commit just like any other commit. Currently this hook is only called for simple commits, so Gerrit user that tries to push a merge commit has to amend it first in order to execute the hook that appends the footer. prepare-commit-msg hook is already called on merge, but commit-msg isn't. It looks like unlike pre-commit not being executed, which was a conscious decision[1], commit-msg was never considered.
