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.

+static void destroy_stash_info(struct stash_info *info)
+{
+       strbuf_release(&info->revision);
+}

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.

+       argv_array_pushl(&cp.args, "diff-index", "--cached", "--name-only", "--diff-filter=A", NULL);

+static int update_index(struct strbuf *out) {

The opening bracket should be on its own line.

+       struct child_process cp = CHILD_PROCESS_INIT;

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

+       cp.git_cmd = 1;
+       argv_array_pushl(&cp.args, "update-index", "--add", "--stdin", NULL);

+               argv_array_pushf(&cp2.env_array, "GIT_INDEX_FILE=%s", stash_index_path);

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

+               res = run_command(&cp) || run_command(&cp2);

Thanks.
