Thanks for mentioning mark-sexp; it was accidentally omitted in my patch. I agree that this particular condition in mark-sexp merits special treatment; the reason for not being able to extend the mark may be far from the cursor and even off-screen.
It is probably worthwhile to communicate the "unbalanced parenthesis" case differently.

For those wondering what this is about: the condition arises when C-M-SPC is pressed with point before an unbalanced left bracket.
