pyenv-update was failing for me with the following errors, even though I had no local changes:

I've updated the script to use --porcelain instead of --short.
From the man page:
"       --porcelain
           Give the output in an easy-to-parse format for scripts. This is similar to the short output, but will remain
           stable across Git versions and regardless of user configuration. See below for details."
