Subject: t8001/t8002: blame: add tests of -L line numbers less than 1
X-Git-Tag: v1.8.5-rc0~166^2~1

t8001/t8002: blame: add tests of -L line numbers less than 1

git-blame -L is documented as accepting 1-based line numbers. When
handed a line number less than 1, -L's behavior is undocumented and
undefined; it's also nonsensical and should be rejected but is
nevertheless accepted. Demonstrate this shortcoming.
