Please keyword app-emacs/mic-paren-3.7. "Mic-paren is an extension to the packages paren.el and stig-paren.el for Emacs. When mic-paren is active (it is activated when loaded) Emacs normal parenthesis matching is deactivated. Instead parenthesis matching will be performed as soon as the cursor is positioned at a parenthesis. The matching parenthesis (or the entire expression between the parenthesises) is highlighted until the cursor is moved away from the parenthesis."

Added ~amd64.
