Yes, I currently set DEFAULT_PAGER to 'more' in my config.mak file
on both of these platforms.  The 'more' on IRIX is decent (it can go
backwards), but the 'more' on Solaris sucks.  I've seen 'less' on some
newer versions of Solaris.  Is it a standard component yet?

So, I think it's appropriate to set DEFAULT_PAGER on IRIX.  There can't
be many users anyway.  It's probably appropriate to set it on Solaris
too, if 'less' is not a commonly installed component on modern systems.
I wonder how surprised existing git users will be, for those on Solaris
platforms that have 'less' installed, when Solaris's crappy 'more'
becomes their pager.

Actually, there is a 'more' in /usr/xpg4/bin that is much better, but
it is not being used when DEFAULT_PAGER is set to 'more'.  Junio
created the SANE_TOOL_PATH hack to add this additional path to the
search path, but it is only implemented in git-sh-setup, so it only
has effect for git scripts.  Maybe it should be added to setup_path().

But, I also think it would be nice if git fell back to the 'cat'
behavior when it fails to spawn the pager, because the following error
is not very informative:

   casey@<a_solaris_box> # git log
   sh: less: not found
   Broken Pipe
