Linus TorvaldsI've just fixed two annoyances of mine with git-diff-tree, which sadly caused me to break some syntax.
In particular, diff-tree for some unfathomable reason (probably incipient braindamage in yours truly) used a single dash "-" to mark the end of command line arguments, rather than the "--" that everybody else uses.
I hope nobody depended on it, because I fixed it.
The other thing I did was to allow a single SHA1, and then consider that to be equivalent to a one-line "--stdin" thing. Ie you can now do
git-diff-tree -v -p HEAD
and it will do what you'd expect it to do, ie it should be equivalent to
cat .git/HEAD | git-diff-tree -v -p --stdin
(apart from a silly bug which I'll fix shortly).
The latter means that if you actually want to track a _file_ named HEAD (or anything else that might trigger as a reference), you'd need to do
git-rev-list HEAD | git-diff-tree -v -p --stdin -- HEAD
but I'm considering making the single-dash thing be equivalent to the combination "--stdin", and not allow SHA1 naming after it, so that this could be shortened to just be
git-rev-list HEAD | git-diff-tree -v -p - HEAD
(but I wanted to make the "-" semantics change be a two-phase thing).
