    _______________________________________________________

Details:

octave_config_info() should treat the configuration information as read-only
data.  Instead, if you ask for a non-existent piece of configuration
information the key is created and the value is not set to anything.  This
seems to have been a problem all the way back to the 3.2.X series.

Example:


more off
octave_config_info ("JUNK")
octave_config_info

---After many variables go by---
    mac = 0
    windows = 0
    JUNK =

error: octave_base_value::print (): wrong type argument `<unknown type>'
