Regex preprocess commit messages

[hypervtechnics]

Is your feature request related to a problem? Please describe.
Our CI system prepends all changes which are merged by using the PR functionality (by policy everyone has to do so) with "Merged PR xxx: ". This does not comply with the conventional commit message format.

Describe the solution you'd like
Something like a commit message preprocessor which enables us to remove or select certain parts of the commit message/body to be used in the following processes.

Describe alternatives you've considered
Removing that prefix, which is unfortunately not possible.

This is implemented in 64317f2. See commit_preprocessors.

For your specific example, now you can do something like this to remove the prefix:

[git]
commit_preprocessors = [
    { pattern = 'Merged PR #[0-9]: (.*)', replace = "$1"}
]
