After this, the function returns. The original did not add to the
table the object name we are looking at, but the new code first adds
it to the table with the unconditional kh_put_sha1() above. Is a
call to kh_del_sha1() missing here ...

... like this one, which seems to compensate for "ahh, after all we
realize we do not want to add this one to the table"?

It is somewhat unclear what we are getting from the split of the
main part of this function into *_1(), other than the *_1() function
now has a very deep indentation inside "if (!found_pack)", which is
always true because the caller always passes NULL to found_pack.
Perhaps this is an unrelated refactoring that is needed for later
steps and does not have anything to do with the use of new hash
function?
