I'm sorry, but I've found a mistake in my code for case:
diff --git a/tg-patch.sh b/tg-patch.sh
index db1ad09..d701c54 100644
--- a/tg-patch.sh
+++ b/tg-patch.sh
@@ -17,8 +17,8 @@ while [ -n "$1" ]; do

So here is corrected patch:
From: Kirill Smelkov <kirr@xxxxxxxxxxxxxxxxxxx>
To: Petr Baudis <pasky@xxxxxxx>
Cc: martin f krafft <madduck@xxxxxxxxxxx>
Cc: Git Mailing List <git@xxxxxxxxxxxxxxx>
Subject: [PATCH (topgit)] tg-patch: add support for generating patches against worktree and index
This implements `tg patch -i` and `tg patch -w` to see current patch as
generated against not-yet-committed index and worktree.
NOTE: unfortunately `git cat-file blob <file>` does not provide an option
to cat file from worktree (only from an object or from index), so I had to
unroll my own `cat file topic:file` with special support for '(i)' and
'(w)' topics.
