hdl-interfaces cannot recognize specific names for vector signals

[caosjr]

hdl-interfaces cannot recognize vector signals with the following pattern:

• interfacename*

However, it is able to recognize vector signals with the following pattern:

• interfacename_*

How to reproduce it:

.. hdl-interfaces::
    :path: library/jesd204/jesd204_tx

    * - tx_phy*
      - n-th lane of the JESD204 interface (``0 <= n < NUM_LANES``).

Solved in 7f7e739 by updating the pattern matching; also iterate twice to catch depth 2 signals, e.g. signal_12_4.
