Prefixing `#` to commit message makes it a Header

Commits on Bitbucket account can be integrated with Issues under Issue tracker by adding #[issue_number]}}in the commit message. This functionality works fine if {{#[issue_number] doesn’t start the commit message, as shown below:

Also affect any # in the commit
