It usually is a good idea to prevent whitespace splitting by the shell
(and especially with things that might unexpectedly be empty, in which
case they end up as "no argument" and not an empty one). So yeah, this
is an exception.

I think we have test_line_count exactly because of this unportability
with wc output.
You'd want:
git ls-tree refs/notes/commits >actual &&
test_line_count = 1 actual
or similar.
By the way, the point of that "ls-tree" appears to be to check the
number of total notes stored. Since notes are stored in a hashed
structure, should it be "ls-tree -r"? Otherwise, we see only the leading
directories; two notes whose sha1s start with the same two characters
would be considered a single entry.
