@johnynek Failing test in globifier...

[error] x Globifiers should
[error] x handle specific hand crafted examples
[error] 'List(/2014/06/30/, /2014/07//)' is not equal to 'List(/2014/06/30/, /2014/07/01/00)' (DateTest.scala:250)

Do you know the lineage of https://github.com/twitter/scalding/blob/develop/scalding-date/src/main/scala/com/twitter/scalding/Globifier.scala#L37

looks very old. I think its taking the range to be an exclusive upper bound but its actually an inclusive upper bound on the range?

I don't remember the history of this line at all. Better comments on something so tricky would be good. More tests pass now, so I guess we should merge, but I am also concerned that the random tests never failed but this one did. I wonder how strong our random tests are. I added an issue: #1091
