[Koha-patches] [PATCH] Bug 8566: Enable koha-foreach to insert the instancename into commands

[Reed Wade]

koha-foreach has been modified to replace __instancename__ with $name
on each iteration using sed.

The docbook file for koha-foreach has also been updated to reflect the
new functionality.

To test:

    koha-foreach ls -ld /etc/koha/sites/__instancename__

should list directories instead of giving an error message.
