It's indeed "git commit" that takes tons of memory, but for all the wrong
reasons. It does a "git diff-tree" to generate the diffstat, and *that* is
extremely expensive:
git-diff-tree --shortstat --summary --root --no-commit-id HEAD --
I suspect we shouldn't bother with the diffstat for the initial commit.
Just removing "--root" migth be sufficient.
Yes and no. It was added as a response to sugestions from
people in "baby step tutorial" camp.
An option to disable the last diff-tree step, just like git-pull
has --no-summary option, would be perfectly fine, though.
