Debian-live manual: bad advice and bad URL

[Lou Poppler <loupoppler@cableone.net>]

I would like to point out 2 small corrections to the debian-live manual
http://debian-live.alioth.debian.org/live-manual/stable/manual/html/live-manual.en.html

At this point I am far from able to create and commit changes myself,
so I offer them to this list, hoping someone else might propagate them.

In section 4.2 the URL given for older, upcoming, and unofficial live images
http://debian-live.alioth.debian.org/cdimage/release/
is 404.  I would suggest instead listing this URL:
https://cdimage.debian.org/cdimage/

In section 4.5.3 the suggestion for adding a partition to extra space at
the end of a live image USB stick says to use parted or Gparted.
For the current live images, with a xorisso-style partition layout,
(for example the file debian-live-9.2.0-amd64-kde+nonfree.iso)
parted (as of 3.2-17) and gparted (as of 0.25.0-1+b1) do not detect
the first partition, containing the entire .iso, they only notice
the small 500KB EFI partition 2, embedded inside it.  They see the
first partition as empty space, and will allow using the space after
partition 2 in creating a new partition 3.  Thus these programs are
no longer appropriate in this case.  Regular old fdisk (as of 2.29.2-1)
works correctly for this; gnome-disks (as of 3.22.1-1) works correctly
for this.  These 2 would be good suggestions for this section of the
webpage.  I also checked KDE partitionmanager (as of 3.0.0-1) and it
does not see the partition 1, and incorrectly offers to include part
of it in a new partition, like parted on which it is based I think.

Thanks to anyone who can help update this documentation.
