If you look at other ports, most use 7 digits.

The version downloaded using GH_TAGNAME should have the same structure 
as releases, unless the project structure itself has been radically 
changed between releases. The top folder name is going to be different 
for GH_TAGNAME. A release is just an alpa-numeric tag in a sequence of 
commits, nothing more.
