I like this change in principle, but I think you could simplify the code a little bit (see my comments in line).

usr.sbin/freebsd-update/freebsd-update.sh
1953

Could you please refactor this to something like:

cat - modifiedfiles <<- EOF | ${PAGER}

The following files are affected by updates,
but no changes have
...
EOF

instead?

  • Use HEREDOC/cat instead of multiple echos

This is indeed much nicer.

One last change request -- could you please use ${PAGER} instead of $PAGER while there? The change looks otherwise fine to me.
