I am not a huge fan of exposing undocumented implementation details
to the test scripts that much. There are three in t13xx series that
mention GIT_CONFIG_PARAMETERS, but these are about testing the config
mechanism itself.
An end-user script would instead be doing "git -c var=val" for each
invocation but this one is being lazy because it does not want to
bother identifying which "git" invocation needs the treatment and
also it does not want to keep maintaining it, which is understandable,
but it feels dirty.
This makes me wonder if core.printsha1ellipsis should really be a
configuration variable in the first place. Wouldn't an environment
variable be more appropriate? After all, the users of scripts that
would be broken by this series would need to the same thing as what
we do to our tests to keep them working while they update them.
