Trying to delete some of the group with special character from the ranger 
admin, but not able to delete.
This issue happens only if there is & in the username:
groupspecial#$@&

i see this error saying this user is not found, user does not seems to be 
parsed correctly at the time of deletion, groupspecial#$@& is the username 
whereas ranger tries to delete "groupspecial":
