I updated this wording in the latest version, to properly describe the
current behaviour.

I think I'll change "-k all -c" to do that.  This is not exactly the
same as the old behaviour, because kernel packages may explicitly
disable initramfs generation during installation and initramfs-tools
used to remember that.  But I think it won't be too surprising that
"-k all -c" really applies to all installed kernel versions in future.

You can't have everything.  Where would you put it?
