[Nix-dev] Emacs 24

are you sure that this information is accurate? I just built an Emacs24
without the ImageMagick dependency, and still all these features seem to
work fine.

How about this: we remove those additional dependencies that were added
relative to Emacs23, and then we wait for someone to speak up, saying
that there is an actual use case that doesn't work anymore? 

Take care,
Peter
