This commit thus adds a new way of adding config entries via the
environment which doesn't require splitting of keys and values. The user
can specify an config entry's key via `GIT_CONFIG_KEY_$n` and a value
via `GIT_CONFIG_VALUE_$n`, where `n` is any number starting with 1. It
is possible to add multiple entries via consecutively numbered envvars
`GIT_CONFIG_KEY_1`, `GIT_CONFIG_KEY_2`, etc, where each of the keys may
have a matching value.

When no matching value exists, it's assumed to be
the empty value.

Is this a good choice of default in the face of potential mistyping when
entering commands, or cut&paste editing of scripts. It's easy to see
cases of mismatched KEY_2 VALUE_1 entries.

Wouldn't it be better to warn about un-matched key/value pairs?

Good point. I'll change this on the next iteration.

+GIT_CONFIG_KEY_1,GIT_CONFIG_VALUE_1::

Shouldn't the man page entry indicate that it's '<n>'  ?

I wasn't quite sure how to document it, but using `<n>` would indicate
better that this can be multiple envvars.
