I've just discovered this bit of documentation. Within the git-var
manual page is this entry:
GIT_PAGER
Text viewer for use by git commands (e.g., less). The value is
meant to be interpreted by the shell. The order of preference is
the $GIT_PAGER environment variable, then core.pager configuration,
then $PAGER, and then finally less.
This suggests that the ordering is GIT_PAGER > core.pager > PAGER >
default.
