Re: To page or not to page

Hmm. How about doing things this way?

 - at the beginning of handle_options() remember argv[0]

 - restructure handle_options() so that it does not run setup_pager() and
   setenv("GIT_PAGER", "cat", 1) inside the loop, but instead remember
   what we had on the command line;

 - after the handle_options() loop, if we saw an explicit --pager,
   --no-pager, that's the decision;

 - otherwise:

   - look at argv[0] to see what the command is;

   - do the config thing to see if there is user preference; if there is
     one, that setting decides;

   - otherwise:

     - see the built-in defaults;

 - and finally use or not use pager depending on what we found above.

I suspect we would want a similar restructure of handle_options() loop about --git-dir and --git-work-tree so that the loop is only used to decide what to do and action is carried out after the loop exits, but that is a separate topic.
