include:
* Drop support for "-b=..." and "-t=..." which are transformation options
that are not supported by BSD install.
* Add support for "-b" and "-B fmt" to allow backing up existing files.
Only specifying "-b" yields a backup suffix of ".old" and "-B fmt"
allows for sprintf(3)-style backup suffices. Number backups are
supported using awk(1).
version include modifications to the script to pass the regression
test suite in regress/bootstrap-install-sh. This makes the installed
install-sh script more closely match NetBSD's /usr/bin/install.
