What do you mean with "global-bindings"?  Probably not bindings in
`global-map', because `define-key' can of course bind keys in
`global-map'.

This will modify `eshell-mode-map', the map used by eshell-mode.  This
is probably not what you want.  Better use a separate map, it set
`eshell-mode-map' as parent map to inherit from it.
