I've attached an updated version of the patch. It will fix this. The glob
engine shouldn't return a dequoted version of the pattern unless it
matches something (and, based on historical behavior, maybe not even then).

list about how backslashes in shell patterns should behave. It's always
fun to shoot at a moving target.
