We know that the bash completer automatically handle colon by preceding it with an escape character backslash. While our bash autompletion file vsh completes multiple items, In case there're multiple items which have same prefix and the content of completion items contain colon(say mac address), The vsh needs to correctly hands the backslash which are added by bash completer, Otherwise the completion won't be successful. This patch fixes this problem. e.g.: # virsh domiflist --domain VM Interface Type Source Model MAC ------------------------------------------------------------- vnet0 network default virtio 52:54:00:fb:7b:f5 vnet1 bridge br0 virtio 52:54:00:80:1b:21 Before: # virsh detach-interface --domain VM --mac <TAB> # virsh detach-interface --domain VM --mac 52\:54\:00\:<TAB><TAB> After: # virsh detach-interface --domain VM --mac <TAB> # virsh detach-interface --domain VM --mac 52\:54\:00\:<TAB><TAB> 52:54:00:80:1b:21 52:54:00:fb:7b:f5 # virsh detach-interface --domain VM --mac 52\:54\:00\: Signed-off-by: Lin Ma <lma@suse.com> Reviewed-by: Michal Privoznik <mprivozn@redhat.com>
