Well, we had requests like this, and we went forth and back a
bit. Ultimately, the way we invoke the pager implicitly for doing
auto-paging is different from manually started pagers (since we want the
mode where the pager is shortcut when the data is short, and since we
optionally want to jump to the end), hence I think it is the right thing
for us to override $LESS instead of using the normal user-configured
$LESS. This way the normal $LESS is left to be the settings for manually
started pagers, but not for our auto-paging. Now, if we'd $SYSTEMD_LESS,
then we could open this up for user control, so that people can even
override the $LESS value for auto-paging. hence I'd be happy to merge a
patch for this.
