That's better! With a HEAD: , that code does a lot of: 

Warning in untar2(tarfile, files, list, exdir) :
  checksum error for entry 'file...'

for each file it tries to extract, but at least it is extracting the files. I wasn't entirely sure about the notation used in the man page - is
"v1.4.0^{tree}" same as "v1.4.0:" ? "HEAD:" is clearer, as most people has a HEAD...
