I've talked to HP, and they would like to keep (HP|HPE), since they feel
that it's more obvious to readers. They are fine with whatever anchors
we feel should be added to the regular expression. I personally don't
think it matters much. Most of our vendor strings are unanchored and
since the product string must also match, it seems unlikely to cause
issues.

Do you have a strong feeling on this? Otherwise, I'm fine with the
config as they gave it to me.
