Completing configuration sections and variable names for the stuck
argument of 'git clone --config=<TAB>' requires a bit of extra care
compared to doing the same for the unstuck argument of 'git clone
--config <TAB>', because we have to deal with that '--config=' being
part of the current word to be completed.

Add an option to the __git_complete_config_variable_name_and_value()
and in turn to the __git_complete_config_variable_name() helper
functions to specify the current section/variable name to be
completed, so they can be used even when completing the stuck argument
of '--config='.

__git_complete_config_variable_value() already has such an option, and
thus no further changes were necessary to complete possible values
after 'git clone --config=section.name=<TAB>'.
