[Fedora-packaging] version in package name with a number in the name

[Patrice Dumas]

Hello,

I would like to package a more recent version of hdf5 (in a private repo,
but the issue is clearly there for EPEL). According to the naming guideline,
with hdf5-1.8.4, the name could be along hdf518. But this is a bit annoying.
Wouldn't it be better to have an exception and allow hdf5-18?
