Feature request : "process lines"

[bligny]

Would it be possible to add the "Process Lines Containing..." feature that exists in TextWrangler.

which allows matching lines to be

• deleted
• or copied (to clipboard or to a new document)

I'm now fully occupied with migrating the whole codes in CotEditor to Swift and the new CotEditor 3 that will be released in this autumn (or winter). So, there is not enough room for adding large new features until finishing them up.

However, well, after that, I wanna add some features to process text easily and handy (e.g. #470). I'm not sure TextWrangler's "Process Lines Containing..." is the best way (I feel the usage of it is too limited.) At this moment, I just can say it is under the consideration.
