I looked at git help and man git, but it is still unclear because if I 
do the first one where I checkout using the tag, I cannot git pull at 
all; I get an error, about not enough information to merge.  However, if 
I use the name of the branch I can now do git pull when changes are 
committed to denzil.  That's why I thought I understood it.  But who knows.
