git show command missing

[driusan]

4 of the remaining 6 test failures from the t0000-basic tests from git are failing because the test suite uses git show -- pretty=raw in order to verify the commit from commit-tree, which is missing

If anyone wants to take a stab at this, I added https://github.com/driusan/dgit/wiki/Adding-a-git-subcommand to the wiki with instructions on how to add a new subcommand.

I can pick this one off next. It seems that if we have a show command that can at least show the commit information, minus the diffs it would allow the tests to do their validation at least. Diffs seem more complicated because I don't think that dgit can yet support diffs within objects.

Yeah, I don't know why they use show and not cat-file, but ignoring the diff and adding a note in status.txt about it is fine. If you want the diff, you need to use the diff-tree plumbing command, and then on the cmd side you can run printDiffs on the result.

I have an initial implementation available in #48
