It isn't about saving space. When I ssh into a machine and need to edit a file I use tabs to indent. Those machines usually don't have a vim config deployed and for bash scripts - who cares. It becomes messed up if you need to edit python files. First check which indendation is used (chances are, that the file was created there, not with an IDE), then use either the tab key (maybe some editor magic makes spaces if spaces are detected for indendation) or space, which makes it more annoying.
