Jeff King d1f884986d git_config_push_parameter: handle empty GIT_CONFIG_PARAMETERS 
The "git -c var=value" option stuffs the config value into
$GIT_CONFIG_PARAMETERS, so that sub-processes can see it.
When the config is later read via git_config() or similar,
we parse it back out of that variable.  The parsing end is a
little bit picky; it assumes that each entry was generated
with sq_quote_buf(), and that there is no extraneous
whitespace.

On the generating end, we are careful to append to an
existing $GIT_CONFIG_PARAMETERS variable if it exists.
However, our test for "should we add a space separator" is
too liberal: it will add one even if the environment
variable exists but is empty. As a result, you might end up
with:

   GIT_CONFIG_PARAMETERS=" 'core.foo=bar'"

which the parser will choke on.

This was hard to trigger in older versions of git, since we
only set the variable when we had something to put into it
(though you could certainly trigger it manually). But since
14111fc (git: submodule honor -c credential.* from command
line, 2016-02-29), the submodule code will unconditionally
put the $GIT_CONFIG_PARAMETERS variable into the environment
of any operation in the submodule, whether it is empty or
not. So any of those operations which themselves use "git
-c" will generate the unparseable value and fail.

We can easily fix it by catching this case on the generating
side. While we're adding a test, let's also check that
multiple layers of "git -c" work, which was previously not
tested at all.
