Subject: [PATCH 1/1] cli/bash-completion: escape spaces in profile names (rh
 #1041901) (bgo #709426)

We need to escape spaces and quotes in connection names, so that a connection
name containing spaces (quotes) is regarded as a single argument by bash.
See e.g. http://stackoverflow.com/questions/1146098/properly-handling-spaces-and-quotes-in-bash-completion

https://bugzilla.gnome.org/show_bug.cgi?id=709426
(cherry picked from commit b911d663d8a9df739a9311efe99c21af362c5738)
