Someone else's customized live build - config options not in the docs

[Zack Weinberg <zackw@cmu.edu>]

I am trying to customize an already-customized live CD (Tails:
https://tails.boum.org/contribute/build/ ) and getting stuck on errors
which suggest a version-skew issue, but I can't prove it.
Specifically:

Was there ever a version of live-build that recognized the config
options --binary-indices, --includes, --packages-lists=standard,
--syslinux-menu, --syslinux-splash, or --syslinux-timeout?  None of
these appear in the documentation.

Was there ever a version of live-build which automatically added
auto/scripts to the PATH when executing auto/*?  This custom build's
scripts appear to assume that this will happen.

I have a sid host system, so live-build 3.0.5-1.  A transcript of the
failing 'lb config' operation is appended.  Thanks in advance for any
help.  Please cc: me, I'm not subscribed.
