Subject: [PATCH] readObjectHeader: Allow extra whitespace before "obj"

The header being read has the format:

    <idnum> <generation> obj

where `<idnum>` and `<generation>` are integers.
Previously an arbitrary number of spaces was being allowed between `<idnum>` and `<generation>`, but not between `<generation>` and `obj`.
We now allow arbitrary spaces between `<generation>` and `obj`.
