pager: move more behavior into core

This moves the global flag and the --pager=yes logic into core. Only
functionality change is that users now always get a --pager flag and
can enable the pager via the flag without the extension active.

Moving the flag into core exposes a defect in the ro localization,
which will have to be corrected later.
