[PATCH v2] Documentation/config: note trailing newline with --type=color

[Taylor Blau <me@ttaylorr.com>]

In 63e2a0f8e9 (builtin/config: introduce `color` type specifier,
2018-04-09), `--type=color` was introduced and preferred to the
old-style `--get-color`.

The two behave the same in almost every way, save for the fact that
`--type=color` prints a trailing newline where `--get-color` does not.
Instead of introducing ambiguity between `--type=color` and the other
`--type` variants, document the difference between `--type=color` and
`--get-color` instead.
