too many branches?

[Tobias Gruetzmacher]

Hi,

I was trying to index some large repositories with a mass of release and feature braches (80 to be exact) and ran into the error

indexGitRepo(/PATH): too many branches

I can see in

zoekt/indexbuilder.go

Line 189 in 4f1f1ef

 if len(desc.Branches) > 64 { 

that the maximum is 64 branches. Is this a technical limitation? Can I raise the limit without ill effect?

the branches are used in a int64 bitmask, so we would need to reorganize some code to use []byte instead and support a variable number of branches. PR appreciated.
