Thanks, pushed to the master branch.

In the future, please make sure the commit log entries indicate the
function in which each change was made.  E.g., here:

  * lisp/progmodes/bat-mode.el: Set comment-start-skip.

the function is bat-mode, so the log entry should have said

  * lisp/progmodes/bat-mode.el (bat-mode): Set comment-start-skip.

You can use "C-x 4 a" to format the commit messages for you.
