Format the commit message to follow "ticket: short comment" pattern.

fix_commit_msg.sh

git filter-branch --msg-filter 'perl -e '\''while(<>) {print join(q/: /, split(/\s*:\s*/, $_, 2))}'\''' -- --all
git for-each-ref --format="%(refname)" refs/original/ | xargs -n 1 git update-ref -d

The ''' (single quote, backslash, two consecutive single quotes) is the bash way to indicate a single quote embedded in another single quote. This is necessary as both the --msg-filter and -e of Perl expect the command be single quoted.

Here is test case for the commit message command:

cat << EOF | perl -e 'while(<>) {print join(q/: /, split(/\s*:\s*/, $_, 2))}'
