Add « and » as a selection word boundary

[yorickvP]

I'm currently using a custom regex to treat nix store paths as a word in alacritty. If I double click a nix store path in ghostty (e.g. «derivation /nix/store/ghickzjb9c8hf4a8jg7p6apsz2d2sgvd-boost-1.81.0.drv»), the » is also selected.

An easy fix would be to add « and » as a word boundary.

I have yet another opinion on what should constitute a word boundary. Since there seem to be a lot of different opinions on how this should work, could it be made configurable?

Easiest would be to just make boundary configurable. If you're looking to "standardize", VTE might be a good behavior to mimic. Its home page page lists a few terminals that use it, and Ptyxis does too. VTE supports configurable word boundaries with word_char_exceptions. It's sort of the opposite of Ghostty's implementation. You specify characters that should not be considered a word boundary.
