Was a bit short here, trying to do too much at once. Was also wrong, as
bug was in the 'all' section :).
To give a longer explanation, if you have a _full_ NVR for a package
you can split it fairly easily:
N-V-R
==
N, V, R = input.rsplit('-', 2)
==
name: N
version: V
release: R
a-a-a =
name: a
version: a
release: a
a-a-a-a-a-a =
name: a-a-a-a
version: a
release: a
a-a-a-a-b-c =
name: a-a-a-a
version: b
release: c
a-b-c-d-e.f-a =
name: a-b-c-d
version: e.f
release: a
...but if we add wildcards, we are completely screwed because it's
mostly not possible to work out what the * is hiding.
Eg.
*-a-a matches the name of "a-a-a-a" (version b-c) and the
version-release of "a".
a-*-a matches "a", "a-a-a-a" (version a-a) and "a-b-c-d".
