I'm trying to use diff-tree --stdin to diff several trees in one go.
But I just get error messages when I feed it two space-separated trees
(one commit works fine):
$ echo $(git rev-parse HEAD^{tree}) $(git rev-parse HEAD^^{tree}) | git diff-tree -p --stdin
error: Object 7bfd9971f77438858e412be0219ec78afb3ca46f not a commit
This is at odds with the documentation:
--stdin::
When '--stdin' is specified, the command does not take
<tree-ish> arguments from the command line. Instead, it
reads either one <commit> or a pair of <tree-ish>
separated with a single space from its standard input.
I tried reading the code to figure out what's wrong, and as far as I
can tell the code to do this is there, but seems to be protected by
logic that aborts everything unless the whole input line is a valid
commit. Or maybe I'm just confused ...
