archive.targz_pack does not work if you have a single glob followed by double glob

I am trying to archive the contents of a directory whose name I only partially know. In this patch, I tried to specify this using mms/server/* mongod-ftdc-logs/ ** but this did not work. Looking at the Go code, it looks like the first glob is not expanded and thus don't archive anything.

Is it possible to add functionality to support this case?
