koji list-tag-inheritance shows a compact view of the inheritance tree flags. These can be .... or .F.., etc.

Here's an example of tag inheritance that includes a pkg_filter setting on one relationship:

koji list-tag-inheritance tools-rhel-7-compose
     tools-rhel-7-compose (7483)
....  ├─tools-rhel-7 (8606)
.F..  │  └─eng-rhel-7 (5067)
....  └─othertools-7E (5914)

The problem is that koji list-tag-inheritance --help does not explain what the F means there.

The --help text should provide users with the following information:

1) Explain what each single-character flag means

2) Explain how to get more details about a particular inheritance relationship (for example, I see F here, but how do I discover what that exact pkg_filter regex is?). I think the only way to get this information for now is to run koji call getInheritanceData tools-rhel-7
