Share indentation improvements to other plugins with Clojure-based indentation

[axvr]

There are several Vim plugins for other Clojure-like Lisps that were forked from Clojure.vim or Vim-clojure-static that could benefit from the upcoming indentation improvements.

• vito/bass.vim
• janet-lang/janet.vim
• bakpakin/fennel.vim

Either open an issue letting the maintainers know, or open a PR porting them to the new algorithm.
