The commit message in this patch and the following ones could be a bit
more verbose. It could at least tell that the end goal is to convert
git-stash.sh to a C builtin.

Not sure if "destroy" is the right word in the function name. I would
have used "free" instead.

The brackets are not needed.

Maybe use strbuf_addstr()?

Spurious new line.

Indent looks weird.

The opening bracket should be on its own line.

Maybe add a new line here to be more consistent with other such functions.

Maybe use small functions for the above read-tree and checkout-index.

Thanks.
