What version of libvirt are you using?  And is this within the virsh
batch mode, or from the command line?

That's not supposed to happen; quoting of spaces is supposed to mimic
shell quoting, so that you can use arguments with spaces in both command
line and batch mode.  To test:

# virsh echo two  spaces
two spaces
# virsh echo 'two  spaces'
two  spaces
# virsh
Welcome to virsh, the virtualization interactive terminal.

Type:  'help' for help with commands
       'quit' to quit

virsh # echo two  spaces
two spaces
virsh # echo 'two  spaces'
two  spaces
virsh # quit

I'm not reproducing this; I tested with libvirt 0.10.2.2 (Fedora 18):

# virsh snapshot-list fedora-local
 Name                 Creation Time             State
------------------------------------------------------------
 name with  spaces    2013-01-22 09:05:07 -0700 shutoff

# virsh snapshot-delete fedora-local 'name with  spaces'
Domain snapshot name with  spaces deleted
