So, this roughly corresponds to parse_flags_and_rev function, it seems.

Use of strbuf w_commit_rev looks completely pointless here. Am I
mistaken to say that the above three lines are equivalent to:
ret = !get_oid(revision, &info->w_commit);

For the same reason, these strbuf's look pretty much pointless. I
wonder if a private helper
static int grab_oid(struct oid *oid, const char *fmt, const char *rev)
{
struct strbuf buf = STRBUF_INIT;
int ret;
strbuf_addf(&buf, fmt, rev);
ret = get_oid(buf, oid);
strbuf_release(&buf);
return ret;
}
would help here? Then you wouldn't be writing something like the
above, and instead you'd grab four object names like so:
if (grab_oid(&info->b_commit, "%s^1", revision) ||
grab_oid(&info->w_tree, "%s:", revision) ||
grab_oid(&info->b_tree, "%s&1:", revision) ||
grab_oid(&info->i_tree, "%s&2:", revision)) {
... we found an error ...
return -1;
}
which would be a lot easier to follow, no?

Wouldn't it make more sense to get rid of PATH_MAX and hold it in a
strbuf instead? I.e.
static struct strbuf stash_index_path = STRBUF_INIT;
...
strbuf_addf(&stash_index_path, "%s.stash.%" PRIuMAX, index_file,
(uintmax_t)pid);
