Teach show_object_with_name() to avoid writing a space before a name
which is empty. Also teach tests for rev-list --objects --filter to not
require a space between the object ID and name.
show_object_with_name() inserts a space between an object's OID and name
regardless of whether the name is empty or not. This causes 'git
cat-file (--batch | --batch-check)' to fail to discover the type of root
directories:
git rev-list --objects --filter=tree:1 --max-count=1 HEAD \
| git cat-file --batch-check
git rev-parse HEAD: | xargs -I% git cat-file -t %
git rev-list --objects --filter=tree:1 --max-count=1 HEAD \
| xargs -I% echo "AA%AA"
git rev-list --objects --filter=tree:1 --max-count=1 HEAD \
| cut -f 1 -d ' ' | git cat-file --batch-check
The extra space provided by 'show_object_with_name()' sticks to the
output of 'git rev-list' even if it's piped into a file.

I don't see any reason _not_ to remove this stray whitespace at the end,
since it seems like it just gets in the way of easy scripting. I also
think this case will only present itself for root trees.
Not sure if making the whitespace optional is the right solution for the
test, although I couldn't come up with a cleaner approach. Maybe
something like this would be better, even though handling it in the
regex is shorter?
if [[ -z "$name" ]] then
grep "^$hash" actual
else
grep "^$hash $name" actual
