Re: [GSoC] Interest in "More Sparse Index Integrations" project idea

I read the [1] and this "<rev>^-" syntax seems to exclude the first parent of <rev>. In another word, it only gets the part of history within the checked-out new branch, i.e. "This is typically useful for merge commits where you can just pass <commit>^- to get all the commits in the branch that was merged in merge commit <commit> (including <commit> itself)."

It seems that the checked-out branch has a linear clean history, and that's why it looks like "completely ignore '--graph'". Actually, it does not ignore "--graph", e.g.

with "--graph":

* 3c0e417827 Merge branch 'ds/fetch-pull-with-sparse-index'
* 408c51f0b4 test-read-cache: remove --table, --expand options
* c2a2940510 t1091/t3705: remove 'test-tool read-cache --table'
* 3a9a6ac5d9 t1092: replace 'read-cache --table' with 'ls-files --sparse'
* 78087097b8 ls-files: add --sparse option
* 5a4e0547e2 fetch/pull: use the sparse index

w/out "--graph":

Look at the asterisks prefixing every commit in the with "--graph" part. If you init a new repo and add a few commits to form a linear history, you will get a similar result by "git log --oneline --graph".
