pkg repo ignores tgz?

[WAKABAYASHI, Nobutaka]

After upgrading pkg from 1.2.x to 1.3.x, pkg repo ignores tgz-ipped packages.
Is this what pkg meant to do?

$ sudo pkg create -f tgz  sl-5.01
Creating package for sl-5.01
$ ls
sl-5.01.tgz
$
$ pkg repo .
pkg: No package files have been found
Cannot create repository catalogue
$ sudo pkg create -f txz  sl-5.01
Creating package for sl-5.01
$ pkg repo .
Creating repository in .: 100%
Packing files for repository: 100%
$

$ pkg -v
1.3.6
$
