[PATCH] libvirt-guests: avoid globbing when splitting $URIS

[Eric Blake <eblake@xxxxxxxxxx>]

* tools/libvirt-guests.init.sh (start, stop, gueststatus): Avoid
shell globbing, since valid URIs can contain '?'.
---

> Meanwhile, we already know that a valid URI does not contain whitespace
> (a valid URI can represent whitespace via encoding, where needed), so
> it's already acceptable to use IFS splitting on $URIS to break it into
> individual URIs, it's just that we need to suppress globbing in the
> process.  'set -f' can be used for this, if needed.

Does this patch look sane?  If you like it, then I will push your
patch and mine at the same time.
