Yeah. We can fix it up when we encounter new undefined reference
errors (e.g. a new test program that links to libgit.a). Anyway it
does not look too difficult to do. Take it or drop it. Your call.

Makes sense.

Ditto. check_pager_config() is also moved from git.c to pager.c.

These two are big code moves, basically all {fetch,send}-pack code.
While I think this is good cleanup (I get surprise every time I look
at transport.c and it leads to buitin/fetch-pack.c), this is probably
not a good idea if we have on flight topics, which may cause lots of
conflicts for you and Junio. Fortunately we don't at the moment.
