A pager (GIT_PAGER) formats the diff git produces, while
externalDiffCommand and useExternalDiffGitConfig change how git produces
the diff in the first place. They are different pipeline stages, not
alternatives, so combining them on one entry just pipes one through the
other and produces garbled output (e.g. delta trying to parse
difftastic's side-by-side output as a unified diff). The two external
mechanisms likewise conflict, with the explicit command silently
shadowing the git config one. Treat all three as mutually exclusive and
reject configs that set more than one on the same entry.

The plan is to keep the original docs and schema folders unchanged for the
duration of a release; we'll only continuously update the -master copies. Right
before a new release we will copy them over.
