[PATCHv2 1/2] log-tree: properly reset colors

[Michael J Gruber <git@drmicha.warpmail.net>]

Except for the separator, all output items reset the color immediately.
Do the same for the separator.

This affects only cases where setting color A does not override color B,
such as when one is forground and one background.
