This saves the dive data into a git object repository instead of a
single XML file.
We create a git object tree with each dive as a separate file,
hierarchically by trip and date.
NOTE 1: This largely duplicates the XML saving code, because trying to
share it seemed just too painful: the logic is very similar, but the
details of the actual strings end up differing sufficiently that there
are tons of trivial differences.
The git save format is line-based with minimal quoting, while XML quotes
everything with either "<..\>" or using single quotes around attributes.
NOTE 2: You currently need a dummy "file" to save to, which points to
the real save location: the git repository and branch to be used. We
should make this a config thing, but for testing, do something like
this:
echo git /home/torvalds/scuba:linus > git-test
to create that git information file, and when you use "Save To" and
specify "git-test" as the file to save to, subsurface will use the new
git save logic to save to the branch "linus" in the repository found at
"/home/torvalds/scuba".
NOTE 3: The git save format uses just the git object directory, it does
*not* check out the result in any git working tree or index. So after
you do a save, you can do
git log -p linus
to see what actually happened in that branch, but it will not affect any
actual checked-out state in the repository.
