The only reason it's not there is that nobody's ever asked for it ;-)

You can specify an actual list right now instead of a keyword for
branches_to_build. e.g. "branches_to_build => [qw(REL_13_STABLE
REL_14_STABLE REL_15_STABLE)]". The only difficulty about this is you
need to prune the list when a branch goes EOL.

But we could also build in some keyword type settings too, that would
interact more sensibly with the server list of branches.

So we could say something like  "branches_to_build =>
'UP_TO_REL_15_STABLE'". That would be pretty simple to code for.
