Fix handling of filenames with space in bash completion (#341)

Browse source 
By calling __gitcompappend with the same suffix as the completion for git
does (i.e. " ") we can remove the call to sort -u as it is no longer
needed (bash seems to remove duplicates) and then spaces are handled correctly.

Also make the completion available in testhost.
