Hmph.  Is that to help people who uses GIT_PAGER but no PAGER,
or have both but set it differently (setting both and in the
same way does not make much sense).  But what it means is that
"git command --help" and "man git-command" would be paged
differently.  I highly doubt it is really desirable.

What's the reason to set GIT_PAGER and PAGER differently to
begin with?  Can people give examples of the reason why?

By the way, I would understand if there is a request to honor
GIT_LESS environment and if it exists export its value instead
of FRSX as LESS when we spawn the pager.  As some people do not
want S nor R for other programs but do want them for colored git
output that tends to consist of long lines.  This is a slightly
related topic, but different from the issue you raised in your
message.
