I think there are two issues here, but both are solvable:

  1. You want to see _just_ these commits, but not the whole ancestry
     chain. In that case, you want to use --no-walk. E.g.:

       tig --no-walk commit1 commit2 ...

     Though it seems there are a few display artifacts. If I do

       tig --no-walk tig-0.1 tig-0.2

     I get the 2 commits I expect, but also two "extra" blank
     commits at the bottom.

  2. tig works like a pager when stdin is not a tty. You can work
     around this by using xargs to give the commits to it on the
     command line, and then redirect stdin from the tty.

       ... | xargs sh -c 'tig --no-walk "$@" </dev/tty'

     which is kind of a lot to type. It might be nice for "tig -T"
     to open /dev/tty unconditionally instead of looking at stdin,
     so you could just do:

       ... | xargs tig -T --no-walk
