-   Usually, the emitted hook documentation starts with the hook

-   While emitting the doc field, an @findex entry is added

   If the doc field starts with '*', the leading '*' is stripped, and the doc
   field is otherwise emitted unaltered; no function signature/
   @deftypefn/deftypevr/@end is emitted.
   In particular, a doc field of "*" means not to emit any ocumentation for
   this target.def / hook_array entry at all (there might be documentation
   for this hook in the file named IN_FNAME, though).
