Man page says
-i, --extract
Copy-in. Read the archive from standard input (or from the file
supplied with the --file option) and extract files from it, or
(if the -t option is given) list its contents to the standard
output. If one or more patterns are supplied, read or list only
files matching these patterns. The -t option alone implies -i.
But the man page does not mention the -t option. Only --list, but
without explanation. So the user gets confused.
Now turning to the INFO manual,
'-t'
'--list'
[*note copy-in::]
Print a table of contents of the input. Can be used alone, as a
mode designator, in which case '-i' is implied.
Well we have a look at copy-in, but there there is no mention of either
-t nor --list.
