git-save: improve commit authorship data

Browse source 
We used to always just commit as "subsurface@hohndel.org" because
libgit-19 doesn't have the interfaces to do user name lookup.  This does
better if you have libgit-20, using "git_signature_default()" to get the
actual user that does the saving.
