bash supports the same, also named magic-space. For bash you can chuck something like "Space: magic-space" in your $INPUTRC, although you'd probably want a guard(see Readline Conditional Constructs in the manpage).
FWIW, zsh without oh-my-zsh can be configured to do too this with "bindkey ' ' magic-space".
