Bump files, which are being ignored in Git, too

[SchulteMarkus]

Is

• commit-and-tag-vesion does not bump a file, if it is being ignored in Git
• This is done by using https://github.com/bmeck/dotignore, which parses the .gitignore file

Suggestion

In my opinion, there is no reason to not bump a file if Git ignores it. .gitignore does it's job, commit-and-tag-version does (only) it's own. My argument is kind of separations of concerns.

Background

• https://github.com/bmeck/dotignore seems dead
• When using commit-and-tag-version, I ran into a bug of bmeck/dotignore (which I don't report as the project seems dead). This bug ultimately led to the package.json in my project not being updated using commit-and-tag-version. My .gitignore had an invalid entry, which made bmeck/dotignore behave inappropriately. But well, the package.json would have still be updated if commit-and-tag-version wouldn't check for .gitignore at all

This is a good point. I agree with you, I can't think of a reason not to bump files that happen to be in gitignore.

I think we should either:

1. Add an option to disable the gitignore check, or
2. Release a breaking change that disables the gitignore check
