easy-mark doesn't include next sexp on second invocation

[unhammer]

With mark-sexp, you can press it several times to mark sexp's forward, e.g. if you have

(setq |foo '(bar) fie fum)

then after pressing C-M-SPC three times, you'll have marked foo '(bar) fie.

But after (global-set-key [remap mark-sexp] 'easy-mark), pressing C-M-SPC thrice only '(bar) is marked (and it never moves forward no matter how many times I press it).

Once enter the easy-kill mode, the selection can be extended by typing 1,2...9,0 or the char for the thing.

Typing three C-M-SPC without easy-mark is equivalent to typing C-M-SPC s s or C-M-SPC 2 when using easy-mark.
