Don't mix up empty code block with nonexistent one in rule actions.

Turns out that re2c allows empty code blocks:
    /*!re2c
    <a> "a" :=
    */

re2c up to 0.14.3 handled this correctly (generated empty action).
Since then this behaviour has been broken: re2c started to autogenerate
jump to nonexistent condition.
