set open-paren-in-column-0-is-defun-start to nil
Set open-paren-in-column-0-is-defun-start to nil in rust-mode. This
setting is a performance hack in Emacs, at the expense of correctness in
some cases. However, due to the syntax-ppss cache, I doubt whether this
hack is needed for Rust code.
Fixes #107
