Thanks. I've never built Emacs from source. I think it might be easier for me to wait till this patch makes it to the official release.

It's actually pretty easy to build from source. The easiest way (that depends on your platform) is to install the version that corresponds to HEAD. The slightly less trivial way is toget the code from Savannah:

https://savannah.gnu.org/projects/emacs

clone the code and follow the instructions.

I got used to doing that a few weeks ago and it is fascinating to see all the new features pouring in everyday.

It turned out to be relatively easy, so I implemented this on the
master branch of the Emacs Git repository.  There are two new
variables that you should set to "^" to get the behavior you wanted.
I hope you can build the master branch and see whether the new
facilities solve your case.

Thanks.
