Don't close buffers that were previously open and included in the grep

[jtrv]

Maybe add an option whether to leave buffers open after grep-write?

I would love this, I keep getting caught off-guard by buffers getting closed.

This is the behavior with grug, you should try it out!

I'll probably deprecate this in favor of grug since it's better and will also replace grep-expand.kak once I get to it.

However we could add this behavior here by recording / marking open buffers beforehand, then doing a check at the end before deleting each buffer, it shouldn't be hard.

I'll give it a shot!
