Side note, not about this patch: we treat pager.color as a synonym for
color.pager. Is that something we want to document, or is that an
instance of being extra friendly when the user makes a typo?
IIUC, this is the same historical wart that comes from the same
place as diff.color that existed before color.<cmd> wanted to be the
way forward. We do not break existing configuration files by
starting to suddenly reject diff.color or pager.color, but we do not
encourage new uses by not advertising them.
