After further considering PR #21's arguments, the setup script should
not go around setting `color.ui`:
* it shouldn't be needed for recent gits with default compile
settings[0]
* it may override advanced users's own colour configuration/
customisations (or disabling)
* it forces default colours on users for which it may be useless
(colour- blind) or even detrimental (other vision impairments)
* some linux distributions apparently default to idiotic pagers which
can't handle ANSI colour codes by default and spew garbage to the
terminal
