If the chroot is exited with nonzero status, kiss-chroot runs `die
chroot failed`. Then, die runs `exit 1` which causes the trap to
execute. However, in this scope, "$@" is "chroot failed", so the trap
evaluates $1 to be "chroot" rather than the mountpoint given to the
kiss-chroot script. Then, the trap tries to unmount "chroot/dev" etc
rather than the true mountpoint.
This patch uses double quotes rather than single when setting the trap,
so that $1 is expanded then and the mountpoint is stored for when the
trap is called.
kiss' help output will now include all executables found in $PATH
which begin with kiss-*. A comment string is optionally usable via
setting the second line of the script to a string.
Example:
...
This also means that 'kiss <script name>' is also possible now.
If I have a script in my $PATH called kiss-depends, I can now use
it via kiss with 'kiss depends'.
