I confirm there are extra blank lines at the bottom.  As many as real
commit lines.

Thanks for the suggestion.  However, my list of commits is too long,
the shell errors out with "tig: command too long".  I'd like to feed
tig with a list of commits from stdin, or from a file.

Something like: ... | tig --no-walk -F -

Which means: take the list of revisions from specified file, or here -
for stdin, a la grep.
