Show corresponding code for transactions

`?show <transaction>` displays the definition of the transaction code. Now, if you append `#` to the transaction, the corresponding base object of the transaction will be shown.

Examples:

- `?show nwbc#`: display method `cl_nwbc->se93_launch`
- `?show se91#`: display program `rsmessage`
