   Description:

     declare -F yields the wrong line number for a function that has
   nested functions declared within. Instead it gives the line number of
   the last nested function.


   Repeat-By:

     ```

     #!/bin/bash


   set -e


   fn-a() {

     echo "..."

     echo "..."

     echo "..."


     nested-fn() {

       :

     }


     nested-fn2() {

       :

     }


     nested-fn

   }


   shopt -s extdebug

   ln="$(declare -F fn-a)"

   shopt -u extdebug


   echo "$ln" # fn-a 14, should be 5


     ```
