You can as well use prepare-commit-msg hook, which accepts more parameters than commit-msg. Then you can check if the message is coming from a file, a template, etc to avoid appending the issue numbers when you don't want it.

With the following script in .git/hooks/prepare-commit-msg when you are working in a feature branch named foo-123, then [#123] will be added to the third line of every commit you make.

#!/bin/sh

if [ x = x${2} ]; then
  BRANCH_NAME=$(git symbolic-ref --short HEAD)
  STORY_NUMBER=$(echo $BRANCH_NAME | sed -n 's/.*-\([0-9]\)/\1/p')
  if [ x != x${STORY_NUMBER} ]; then
    sed -i.back "1s/^/\n\n[#$STORY_NUMBER]/" "$1"
  fi
