Hrm. Is the problem on the git-executing side, or is it on the setting
up the config side?

Sadly (or perhaps not) I no longer have any Solaris machines to test on.
Can you confirm that "git config pager.external" looks OK inside that
test?  Can you confirm via GIT_TRACE=1 what is being sent to the shell?

Also, it looks like we actually run commands internally from git using
"sh -c". So if it is the executing side that is wrong, I don't see how
/usr/bin/ksh would be involved at all (it would either be /bin/sh, or
/usr/xpg4/bin/sh if you have your PATH set).
