Hmm.  I must not be using git correctly.  Could someone please
recommend a better approach?  From last night's log:

Stop.
[failure]

What I want is the equivalent of "svn revert", to return all files in
the working directory to their state in the repository.  I don't really
want "git stash" but I guess maybe "git stash clear" might work?  

Alternatively, I could "rm configure.ac" and let "git pull" recover it
for me.
