These appear to be two distinct issues.  The document does talk about systems
truncating the #! line, but it discusses separately (in the documentation for
`-S') systems that always run scripts with csh.  As a solution, it quotes a
fragment of sh and csh and Perl code that re-executes the script under Perl.

Good point.  I suspect more systems still in use truncate #! than execute
scripts by running them through csh.
