RFI: Git export of CCR dives

[Willem Ferguson]

I have been modifying the code in save-git.c to be comparable to that in 
save-xml.c.  A few issues arise:

1) After these modifications are finalised I need someone to test the 
code since the git interface is not public.

2) Cylinder pressures in storing samples: the git format does not 
require "pressure=178bar" as in xml, it only uses "178bar" as part of 
the sample data. With the addition of diluent cylinder pressures, the 
situation is a bit more complex. At the moment I changed the git code to 
use a "pressure=178bar" and "o2pressure=145bar" in the sample record, in 
line with the current state of the xml export as well as the structure 
of the sample records. But this breaks the backwards compatibility of 
the code.
Ideas would be appreciated.

Kind regards,
willem
