conf.d script overwrites local modifications about base16-fish

Sorry for the slow response. Somehow I didn't get any notification from my own repo.

I remember this plugin was initially coded to set colors through universal variables. Then it didn't feel alright since there was no simple way to clean them up when the plugin was uninstalled.

But your case sounds very reasonable and I believe there should be a way to handle this more nicely, i.e., making use of event system in Fisher.

Since creating this issue fish introduced the theme subcommand to fish_config. It doesn't solve all the problems (you can still get stale variables after changing themes), but I'm closing this.
