Hello,
I am able to reproduce with mis-indentation on emacs -Q:
Here is an example code:
(require 'cl-lib)
(cl-labels ((categoryp (tag)
(string-match-p "\\`@" tag)))
(categoryp "@a"))
Above is the result of selecting the whole code and C-M-\ (indent-region). Notice that the body of `categoryp' gets indented by the name of that fn.
