I briefly wondered if this helper need to know about contents
conversions (e.g. smudge/clean or crlf), but not doing any of that
*is* the right thing to do. IOW, I agree with what this part of the
patch does.
But it feels, at least to me, that this helper function ...

... and this one are overly specific. Why should they know about
(and limit themselves to operate on) cache-entry type? Isn't it too
much to ask for the caller to say "entry->sha1" instead of "entry"?
I do not have an issue with a "load_blob()" helper that makes sure
what it reads is a blob, though, of course.

I should comment on this one in a separate message after I read it
