This invalidates at least t3900.29, which accesses an unexpanded $3
from the test script. The patch below fixes this case.
I tried to detect other cases by poisoning test_run_ like this:
- test_eval_ "$1"
+ test_eval_ :\; :\; :\; :\; :\; "$1"
in the hopes that ":;" is an error at the place that uses $1, $2, etc.
t3900.2[89] are the only tests that are uncovered in this way.
I noticed this because I have a patched test-lib.sh that calls
test_eval_ in a similarly modified manner.

Subject: [PATCH] t3900: do not reference numbered arguments from the test
script
The call to test_expect_success is nested inside a function, whose
arguments the test code wants to access. But it is not specified that any
unexpanded $1, $2, $3, etc in the test code will access the surrounding
function's arguments. Rather, they will access the arguments of the
function that happens to eval the test code.
Play safe by placing the argument in a named variable.
