Do not dump a glob reference when its location is ghost. (Fix bug #4469)

This patch also causes the code to finish a bit faster in the NoGlob case
by not preparing a string for dump_string. It also optimizes
Dumpglob.is_ghost by only checking whether the end position is zero.

Note that no ghost locations were part of the glob files of the standard
library before the patch. Note also that the html documentation of the
standard library is bitwise identical before and after the patch.
