I like the idea of 'G' to filter hunks. The perl script does not exist since git v2.40.0 so I don't think the installation instructions work for recent versions of git as there is no way to stop 'git add -p' from running the builtin version. I see this is MIT licenced but the code is very closely based on the perl script which is licensed under the GPLv2.

huh. I guess this is a prototype for features that will have be submitted to the upstream version. There was a feature in development for something like `git add -G <regex>`, maybe a decade ago, that never got completed.

As for licensing, I'm happy to change the license. I have no strong feelings on the subject, and don't know what restrictions GPLv2 imposes on a port to another language.

It would be really nice to have this upstream - I don't know if the upstream implementation being in C now makes that easier or harder. As for the license I think because this is so closely based on GPL code it would be safer to use the same license.
