Thank you.

Now, how do I get rid of the unwanted merge object?

Here's my reflog:

The merge object at f2500db is the problem. That's what I want gone.

This repository started with a clone; bec1bbb HEAD@{12} commits a file (or a 
version of it) that was also entered in directly at github. That's on 
origin/master. Now that (I think) I have a better idea of what's going on, that 
commit on origin/master should reflect the 'limonite-placer' branch. (the file 
is an early version of that file, somewhere around the first two commits on the 
limonite-placer branch, and is most definitely out of place on master).

I don't know how to see the history that happened before that clone; there were 
several updates on github before that.

Ahh! "git add ."

That makes "stash" work. Thank you.
