Hmph, the name used to be a good one within the context of
implementation of "git branch" command, but I have to wonder if it
is a specific enough name in the global context of the entire
project.  I also wondered if this sits better in wt-status.c;
doesn't "git status" do something similar?

For now, this should do, as I do not think of anything better.  

Thanks.
