Is there an advantage to doing this over setting the GIT_PAGER environment variable?

(Weirdly, git doesn't seem to honour the PAGER var (which would be even better), although its man page claims it does)

I never used that env variable, but, an advantage is that you can put all your git configs in one file and reuse it across different machines, just like any dotfile.

If you use --local instead of --global, you can configure just for the current repository, useful if may find that delta is or isn't the best choice just for that repository

Less env pollution.
