Re: [PATCHv5 20/23] git notes merge: Add testcases for merging notes trees at different fanouts

Subject: [PATCH] portability fix for [20/23]

    test "$(line generator | wc -l)" = $expected_number_of_lines (bad)

is not portable, as "wc -l" can prefix the number with whitespaces.

Either write the $(... | wc -l) without enclosing in a dq pair, i.e.

    test $(line generator | wc -l) = $expected_number_of_lines (good)

or compare them numerically with 

    test "$(... | wc -l)" -eq $num (ok)

The former is preferred for readability.
