Show gutter diff for 'src' VCS

[Eloitor]

The 'src' VCS is a modern UI for RCS. https://www.catb.org/~esr/src/

Since it is not a very popular VCS, maybe it does not make sense to add build in support for it, but a diff for a file can be obtained using src diff file_name.

Maybe the gutter could be configured to use a user defined command to get a diff...

This is plugins territory. I never heard of this vcs before. We only include git in core because it's ubiquitous.

We also don't shell out to compute a diff but instead use our own git implementation to retrieve the file at head and then run a diff against that on the fly.

So full support for a vcs needs a way to properly check out a file and in the future vcs paths also need to be watched for changes

Ok thanks for the response...
Maybe the command src cat file_name could be used which gets the last commited version of the file.
And let helix compute the diffs.
