Sure, I was trying to do just enough to cover strcasecmp(). I don't
think we need to do black-box testing here.

It's a general established pattern in t1300-config.sh used by several
other existing tests, e.g. the one for bool, path etc. I'd rather not
get into a general refactoring of that file.

Yeah, I was just trying to stick a --type=X v.s. --X test somewhere. I
can add it to another test_expect_success or something.
