description:
When 'attempted_completion_function' non-NULL, with a 'single_match'
match, the expected space is not being added. Problem observed with
"chronyc" and "sqlite3" tab completion. That functionality got
moved to escape_filename() for the !attempted_completion_function
case, but the non-NULL 'attempted_completion_function' case must
also be handled. (Lonnie Abelbeck)
