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.
