That's a bug. Emacs' process has the wrong pgid = when its parent isn't an interactive shell. Here's a workaround for the = same problem using Git. I would hope you can configure Mercurial = similarly. 


Emacs C-g Kills `git = commit` On Mac OS X

2012-02-22

Workaround: Invoke Emacs via = an interactive Bash shell.

emacs.sh:


    #! /bin/bash -i

    emacs "$@"

In a shell:


    git config --global core.editor emacs.sh
