26.1; electric-pair-mode breaks auto-newline minor mode of cc-mode |
|
Date: |
Tue, 18 Dec 2018 12:38:41 -0500 |
When using cc-mode, turning on electric-pair-mode causes the
auto-newline minor mode to stop inserting newlines where expected. This
is relevant to the formatting of C# code with the Allman/BSD brace style
in particular, though it would be nice if these modes specifically did
work together.

Hello, Beatrix.
I have committed the patch from two weeks ago (to the Emacs master
branch), and I'm closing the bug as fixed.
