config: display key_delim for config --bool --get-regexp

The previous logic in show_config was to print the delimiter when the
value was set, but Boolean variables have an implicit value "true" when
they appear with no value in the config file. As a result, we got:

git_Config --get-regexp '.*\.Boolean' #1. Ok: example.boolean
git_Config --bool --get-regexp '.*\.Boolean' #2. NO: example.booleantrue

Fix this by defering the display of the separator until after the value
to display has been computed.
