C-code usually takes a bit

You might ask why I am so eager: For tlmgr I was searching for --byfmt 
like hell, and programmed around it but only for those formats defined
in the tlpdb, not for user added formats in fmtutil-local.cnf. Now
that would have been much easier wiht --byfmt.

No idea if it works or compiles, but it looks reasonable. If someone
which can compile on Win can try it.
