Earlier both "tags" and "heads" were hardcoded there. So now instead of
"heads" we have @wanted_refs.
I suppose I should have given it a better name, like @branch_refs.
Right?

Maybe. I was just looking at Makefile and saw a bunch of configuration
options there, so I just added another one. Haven't noticed the gitweb
config thing. Sorry.
So, we should just hardcode the @wanted_refs (or @branch_refs after the
rename) to simply ('heads'), let it be overriden by perl gitweb config
file and get rid of a new substitution from Makefile?
