Commit hook annoyance

[Eli Zaretskii <eliz@gnu.org>]

Is this really necessary?

  remote: error: hook declined to update refs/heads/gdb-7.9-branch
  To git+ssh://sourceware.org/git/binutils-gdb.git
   ! [remote rejected] gdb-7.9-branch -> gdb-7.9-branch (hook declined)
  error: failed to push some refs to 'git+ssh://sourceware.org/git/binutils-gdb.git'

There  was no unresolved conflicts in the commit I tried to push.  Why
does the hook insist on forcing me to remove the "Conflicts:" part,
instead of looking for the merge-commit conflict markers?  Why do we
care about leaving the reference to original conflicts in the log?
